Why Was the Book Lee the Flea Written?

"All a child needs is one grown-up who believes in them." (Rabbi Shlomo Carlebach)
=============================


People keep asking me why the children's book Lee the Flea is so important to me.

I'll share a very personal story that will explain it in a few sentences... I hope you'll understand!

So, after I recovered from a terminal illness, I decided to leave a keepsake for my children and for other children — one that would make them, and their parents, believe that they are capable of achieving their dreams! And dreams are meant to come true.

I decided to leave it in the form of a story! And since my daughter was 7 and my son was 3... a children's story fit best.
Lee the Flea in the story is actually me!

And Trampoline — is actually Sami and other good people who were there along the way!

And the story behind the story is...

When I was in high school, I kept getting expelled. It was a process that built up over many years... I became a worse student day by day, and the less people believed in me, the "worse" a student I became.

The vice principal couldn't stand me — honestly, I couldn't stand him either — and he kept throwing me out of high school. Even my brothers joked that my mom came to school more often than I did...

After I started in the computer track (a 15-unit major) and made their lives miserable, with an attention disorder they didn't know how to handle, one day they officially told me that at the end of 10th grade — because I was a disruptive kid — I would not continue at the school. After a story I won't detail here, I moved to a vocational school, and I really did sink low — the lowest I could imagine academically.

A few years later, I met the person who went on to change my life...

One day I came to a private high school intending to complete my matriculation, and I planned to register for 3-unit math... At that time there was a principal named Sami, a military veteran.

While I was talking to the secretary, he walked in and asked her and me, "Which matriculation exams did you come to register for?" I told him 3-unit math — and here comes perhaps the most important sentence, the one that changed my belief...

Rabbi Carlebach said, "Every child needs one grown-up who believes in them" — and Sami was the first who believed in me!

Sami is actually Trampoline (the ant) in the story.

He said to me, in these exact words: "Lior, I have a feeling you should be in the 5-unit track, and unfortunately you can't study 3 units here!!! You can go somewhere else — if you study here, it's 5 units only."

From a place where I had never once received encouragement about my studies, suddenly came a person who, in that one sentence, told me I was capable. And that is the key to change... one person who believes in you!!

And I studied, and by the end I scored almost 100 on the 5-unit exam, and later I completed a master's degree in the hardest subject at university...!

And today I understand that this is largely thanks to Sami, the principal!

See how much power the words and the people around us have to change our lives...

The book's role for you — parents and children — is exactly what Sami was for me.

If you have a dream or a wish to achieve something, don't wait for someone to bring it to you — just take action, and the world will help you achieve it.

The Flea Experiment: The Invisible Lid That Holds Us Back — and the Flea Who Refused It

Fleas are, pound for pound, among the greatest athletes on Earth. A creature just 1–3 millimeters long can launch itself roughly 30 centimeters into the air — about 100 times its own body height. If a human being could do the same, we would clear a skyscraper in a single bound. And the takeoff is even more astonishing than the height: a flea accelerates at around 100 g — more than ten times the force a fighter pilot endures — powered by a rubber-like protein in its legs called resilin that stores and releases energy like a coiled spring.

So how on earth can a jumper this extraordinary be taught to stop reaching for the sky? That question sits at the heart of one of the most famous stories in psychology and personal growth: the flea experiment.

What is the flea experiment?

The story goes like this. Take a handful of fleas and drop them into a glass jar. Being champion jumpers, they immediately leap up and out — no lid, no problem. Now place a lid on the jar. The fleas keep jumping, but every leap now ends with a small bump against the glass ceiling. Bump. Bump. Bump.

After a while, something quietly changes. The fleas begin to jump just a little lower — just enough to stop hitting the lid. They have "learned" the ceiling.

Here is the part that makes the story unforgettable: remove the lid, and the fleas keep jumping to exactly the same limited height. The barrier is gone. Freedom is a single leap away. But they never take it. The lid is no longer on the jar — it has moved into their minds. In some versions of the tale, even the next generation of fleas, who never met the lid at all, jumps only as high as their parents did.

Is it real science — or a parable?

It is worth being honest: the flea experiment is best understood as a powerful teaching story rather than a strictly controlled laboratory study. You will not find one definitive peer-reviewed paper titled "Fleas and the Lid." But it was not spun from thin air either — it grows out of a very real practice.

For centuries, fleas were genuine circus performers. Flea circuses were a popular attraction, and trainers really did keep fleas in tiny containers to "break" their instinct to jump away, conditioning them to walk, pull miniature carts, and perform tricks instead. The lid — or the low box — was a training tool. So while the tidy version we retell is a parable, it rests on the true story of the trained circus flea: a champion jumper taught to forget how high it could really go.

The lid is a metaphor — and every one of us has one

The reason this story has traveled the world is that all of us know the feeling of the lid.

We are born with skyscraper-leaping potential. Then life quietly adds a ceiling: a teacher who said we weren't "the creative type," a failure that stung, an offhand comment we never managed to forget, a fear that whispered "people like us don't do things like that." We bump against it a few times — and then, to avoid the pain, we lower our jump. We stop applying, stop asking, stop dreaming quite so big.

And here is the cruel twist the flea experiment captures so perfectly: long after the lid is gone — after the teacher is forgotten, the market has changed, the door has actually opened — we go on jumping to the old, safe height. Nobody is holding us down anymore. We are holding ourselves down.

The flea who refused the lid

This is exactly why we wrote Lee the Flea.

In the book, all the fleas of Fleaville are terrified of ever leaving home — all except Lee, an adventurous young flea who dreams of journeying to the Red Lake, the mythical place where all fleas are said to have come from. When the road ahead turns out to be far harder than he ever imagined, Lee very nearly lets fear win. But then a feisty little ant named Miss Trampoline waltzes into his life, helps him rediscover his courage and confidence, and the two set off on a wondrous, action-packed adventure.

Lee is everything the jar-fleas are not. He feels the fear, he meets the barriers — and he leaps anyway. Miss Trampoline is the friend every dreamer needs: the one who reminds you that the lid was lifted long ago, and that your legs were always built for more.

As the book itself puts it: We too are born into a reality where barriers and dead ends are aplenty. But if we dare to close our eyes, look inward, and take that courageous leap of faith just as Lee did, we may very well discover that not even the sky itself is our limit.

The takeaway — for children and grown-ups alike

The flea experiment is not really about fleas. It is a mirror.

Ask yourself — and ask your children — one honest question: Am I jumping this high because it is truly my limit, or because of a lid that isn't even there anymore?

Find your Red Lake. Take the leap. The ceiling you are so afraid of may have been removed a very long time ago.


Lee the Flea, written by Lior Akirav, illustrated by Efrat Gurkevitch, English translation by Eran Edry. A children's book about daring to dream — and discovering that the sky is not the limit.

Lesson Plan: Jumping Beyond Fear — Inspired by the Book Lee the Flea

Lesson Objectives:

  1. Encourage students to face their fears and overcome them through imagination and perseverance.
  2. Give students tools for positive thinking and an understanding of the importance of effort.
  3. Teach about the power of believing in ourselves, even when the path looks challenging.

Lesson Structure:

Opening — 5 minutes

  • Introducing the book and its messages: We'll briefly explain that the students are about to meet Lee the Flea, a little flea with big dreams. We'll ask the children if they have a dream or a goal they think is hard to achieve.
  • Sharing experiences: We'll encourage the children to share dreams or things that scare them, such as fear of failure or challenging situations.

Part One — Reading the Story — 10 minutes

  • Reading aloud: We'll read Lee the Flea to the end of the book, with short pauses for explanations.
  • Discussion questions:
    • What is Lee trying to achieve in the story?
    • What obstacles stand in his way?
    • How does Lee cope with the difficulty, and what do we learn from him?

Part Two — A Discussion on Fear and Overcoming It — 10 minutes

  • The main discussion: We'll talk with the children about the ideas the book raises:
    • Why do you think it's important to face fear rather than avoid it?
    • Is there a chance we could jump beyond fear and achieve our dreams like Lee?
  • Positive thinking: We'll remind the children that fear sometimes helps us think of safe ways, but it can also be just a stop along the way to success.

Part Three — A Guided Imagery Exercise (Overcoming Fear) — 10 minutes

  • Instruction: We'll ask the students to lie down or sit comfortably, close their eyes, and imagine their fear.
  • Guidance:
    • Imagine the fear as something small and shrunken. Just as the flea looks tiny, our fear sometimes feels big — but we can shrink it in our imagination.
    • Imagine yourselves jumping over that fear, just as Lee jumps far and high, and passing it easily.
    • Deep breaths — feel your courage grow with each breath.

Part Four — Creative Activity — 10 minutes

  • Drawing the dream or the fear: Each student will draw their fear and the way they want to overcome it. They can also draw Lee the Flea jumping over an obstacle or over their dream.
  • Sharing: Anyone who wishes can share their drawing and explain how they intend to cope with the fear or how they see themselves overcoming it.

Closing — 5 minutes

  • Key message: We'll wrap up the lesson with Walt Disney's famous line: "If you can dream it, you can do it." We'll emphasize Lee the Flea's strength and what he teaches us about overcoming fear.
  • An inspiring example: We'll mention other figures like Thomas Edison, the Wright Brothers, or someone who overcame a difficulty and succeeded, like Lee.

Free-to-Use Supporting Materials:

  • Coloring pages: You can print sheets for the children with pictures of jumping fleas or small characters overcoming obstacles.
  • A presentation or handouts to share: If there's a presentation or supporting material, present it as a summary.

Good luck with the lesson!

Lesson Plan: On the Fear of Failure

Lesson Objectives:

  1. Talk about the fear of failure
  2. Coping with the fear of failure — "Everyone experiences fear," "The very act of trying is success!", "Fear — is actually the door that stops us"

Lesson Structure:

Read-aloud, discussion, and worksheets.

Part One

Show the picture of Lee and open with a question:
What do you think the book is about?

Part Two

Ask for 3 volunteers from the class to stand in front of everyone and read the book.
*Notice that some of the children don't raise their hands.

Part Three

Reading the book aloud

Part Four — Discussion

What did you understand from the story?
What was Lee afraid of?
How did Lee succeed in the end?
How exactly did Trampoline help Lee?

Part Five

Talk about the fact that some of the children didn't raise their hands.

About the two common types of fear:

  1. Stage fright (fear of an audience)
  2. Fear of being laughed at

A first option for the key message to convey to the children

This is a safe space where we respect one another and always give credit to anyone who answered and tried, simply for trying.
It's important to remember that the very act of trying is success!
The message is: everyone is afraid to speak in front of an audience, but don't let fear take over — try to speak and to make mistakes,
the very act of trying = success.

Additional Messages — Further Insights

  • You can succeed contrary to what other people think or believe:
    • Examples of people who did the impossible (Edison, Ford, the Wright Brothers...); if there's time, tell about the many failures they had before they succeeded.
Two things related to success:
  • Fear — is actually the barrier / door that stops us from entering and holds us back
  • Imagination and creativity — are the key to the door and to success

If we know what we want and simply close our eyes, dream, and leap with courage — just like Lee — we can do anything. Because it's all in the mind.

Lesson Plan: Helping Others — The Power of Sharing and Mutual Help

Lesson Objectives:

  1. Give students an understanding of the importance of mutual help.
  2. Awaken in students a desire to share and help others, just as Lee the Flea was helped by others along the way.
  3. Encourage each student to find ways they can support those around them.

Lesson Structure:

Opening — 5 minutes

  • Introducing the lesson topic: We'll explain to the children that today we'll talk about a very important topic — mutual help, like the support Lee received along the way in the story.
  • Opening question: We'll ask the children, When was the last time you helped someone? And how did it make you feel?

Part One — Reading Passages from the Book and an Example — 10 minutes

  • Reading: We'll read a passage from Lee the Flea, in which Lee is helped by Trampoline (a symbol of the good people who support him).
  • Short discussion: We'll ask the students:
    • Why do you think Lee succeeded thanks to Trampoline?
    • How do you feel when someone helps you?
    • Why is it important to help others when you can?

Part Two — A Playful Exercise (Mutual-Help Activity) — 10 minutes

  • Pair activity: We'll ask the children to pair up and share with each other a small challenge they've experienced recently — for example, difficulty with a school task, a problem with a friend, or a wish to achieve a personal goal.
  • Advice exercise: Each student will offer ideas or advice on how their partner can cope with the challenge. This strengthens both their ability to listen and their ability to give support and help.

Part Three — An Inspiring Story and a Discussion on Mutual Help — 10 minutes

  • Inspiration from well-known figures: We'll tell about a famous figure who reached success thanks to another person's help — like Sami in Lior's case, in the background story of Lee the Flea. We'll present the figure and ask the students how they feel about the power of mutual help.
  • Group discussion: We'll ask the students:
    • What do you think would have happened if that person hadn't received help?

  • Sharing: Anyone who wishes can share their ideas with the class.

Closing — 5 minutes

  • Key message: We'll emphasize the lesson's message — sometimes all we need is someone to believe in us or help us along the way, and when we help others, we're actually contributing to ourselves too.
  • Closing sentence: We'll recall the sentence "All a child needs is one grown-up who believes in them," and suggest that the students be "that grown-up" for other friends who need them.

Free-to-Use Supporting Materials:

  • Coping with herd mentality
  • The importance of perseverance and effort

Lesson Structure:

Read-aloud — read the book "Lee the Flea" to the class in parts,
after each part there is a discussion and worksheets.

Part One

  • Read the book "Lee the Flea" to the class up to the end of page 10 — "But they all said the same thing: reaching the Red Lake — impossible."
  • Discussion — ask the children what they would do in Lee's place. Would they look for a way? Would they give up and look for another interest?

  • Key message — even though there are fears and difficulties along the way, don't give up.

Interesting Points

  • Fear — is actually the barrier / door that stops us from entering and holds us back; yet it also has an important role: it protects us, for example so we don't get run over in the road...
  • Imagination and creativity — are the key to the door and to success
  • Give examples: Walt Disney's quote: "If you can dream it, you can do it. Remember that this whole thing started with a mouse." Tell the story of Walt Disney, who eventually became an empire and a legend.
  • More examples: the Wright Brothers, Henry Ford, Thomas Edison, Martin Luther King, Armstrong, Herzl.
Present the importance of perseverance and of working on the path you believe in.

Good luck.

Lesson Plan for Kindergartens and Younger Grades — Belief, Dreams, and Self-Confidence

A lesson accompanying the book for younger age groups — Lee the Flea / Lior Akirav

Lesson plan.

It can stand alone, or be part of a series of self-belief books.

About the book:
Lee wants to reach the Red Lake. Everyone around him thinks and believes it's impossible to jump out of the Land of Osh. But Lee doesn't give up, and tries to explore and understand how he's going to do it. One day Lee meets Trampoline the ant, who is the first to believe that Lee is capable. While they play, Trampoline the ant runs and shouts to Lee, and without even noticing he manages to do the unbelievable and reach the Red Lake. At the end of the story, Lee and Trampoline sit happily beside the Red Lake.
The story deals with self-belief — with the idea that where there's a will, the way will always appear. It teaches children the power of belief, and how ordinary, simple things can seem impossible, yet once you do them, they turn out to be simple.

The Main Messages of the Story:

  • Believe in yourself
  • Remember that the right Trampoline always appears to help you achieve your dreams
  • If the will is there and it's strong, the way will always appear
  • Dream big, even if something doesn't seem possible right now
Questions About the Story:
  • How did he not know he could do it at first? Just like in life — until you succeed at something, it seems impossible.
  • Why a flea, of all things? And why this cute little flea? Because it's exactly the one we least expect to succeed — and besides, it's about time people stopped being afraid of fleas.
  • Do you also have dreams you want, but the people around you don't believe in you?

Possible Activities with the Book:

  1. A Lee doll inside a box. Materials: a transparent box, dough or clay, large round stickers and googly eyes, a small red cloth.
  2. For kindergarten children: make antennae, cut out bookmarks, and laminate them. Materials: pipe cleaners, Bristol board, and a stapler.
  3. You can buy a flea doll.

Lesson Plan: Making Dreams Come True

Lesson Objectives

  • The student will think about their dreams and about ways to achieve them
  • Coping with competition and finding one's relative advantage

Lesson Structure

Start by explaining that the book is for children up to age 8, but children in grades 3-5 have also taught lessons with it! In fact, this lesson plan was born from a mother who taught lessons to children in grades 3-5.

That said, we adults also learn a great deal from children's books - the stories are short, 7-10 pages at most, which is exactly why this story was chosen.

Part One

  • Read the book "Lee the Flea" aloud to the class, all the way to the end
  • Discussion - ask the children what the idea of the book is:
    • Never give up
    • Shatter glass ceilings - where there's a will, there's always a way
    • Achieve our dreams

Part Two - What Is Your Dream?

  • Start talking about dreams and ask the children what their dream is.

Part Three - What's the Bad News?

In everything we dream about, there is competition. For example, if a child wants to be a soccer player...
we tell him that every other child in Israel wants to be a soccer player. And so on.

Part Four - The Good News?

If you choose a dream that truly matches your skills, your passion, and your genuine desire
then you'll most likely succeed in achieving it.

For example: if a player truly loves soccer, and manages to score goals in school games,
and goes to a team or club twice a week - then maybe he won't be the best in the world,
but the best in the neighborhood / school / class, or he might play on a soccer team.

Part Five - Dreams Come True

Persevere in what needs to be done, and don't give up!! That is the key to making dreams come true.
  • Talk about how Lee didn't give up and kept his faith, and didn't stay like the other fleas,
  • Talk about the hard work he did (the training) and about Lee's success in the end.
  • Key message - even though there are fears and difficulties along the way, don't give up.
Two things related to success:
  • Walt Disney's quote: "If you can dream it, you can do it. Remember that this whole thing started with a mouse." Tell the story of Walt Disney, who eventually became an empire and a legend. More examples: the Wright Brothers, Henry Ford, Thomas Edison, Martin Luther King, Armstrong, Herzl.
  • Present the importance of perseverance and of working on our dreams!
Good luck

Some Cool Things That Came About in an Amazing Way

One of the funniest things that happened to me: about a week before the book went to print, the ant was called "Ella the Ant." On a day off I met a friend and we decided to go to iJump...

While I was jumping with the kids on the trampolines, I suddenly had the amazing flash of an idea to call the ant Trampoline — because she is Lee the Flea's springboard for making his dreams come true. Right then I edited the story, changed the names, and was wildly excited.

Some flashes of inspiration are born in an amazing way.

Another interesting flash of inspiration :)

Every evening before the book was born, I told my daughter the story, and I wanted Lee to break out through play and joy. I asked my daughter: how should we let Lee the Flea break free?

And suddenly my daughter said they play a game at school... she couldn't remember its name, but it was a really cool idea. The game was Blind Man's Bluff, and that is actually how the idea was born that Lee fulfilled his dream while playing — without even noticing, with his eyes covered, he managed to do the impossible, in a moment of trusting the universe, in a moment of play and joy with his very best friend in the world, Trampoline!

And how were the illustrations of Lee and Trampoline born?

Below are photos from Efrat Gorkevich, the wonderful illustrator, whom I met at a cafe, and together we created Lee and Trampoline and the whole idea... after I had actually asked several illustrators to send me a sample illustration of Lee based on my description...

I received tons of illustrations and chose what the amazing Efrat created... and together we met, refined, and sharpened the characters...

At first I wanted Lee to play the guitar, throw his hand up like a rocker, and shatter a glass ceiling!!!
