big idea
A twelve-year-old can grasp compound interest. The question is whether anyone bothers to draw it for them before they sign their first loan.
Your Money Brain is the book that bothers. It teaches the same math, the same studies, the same psychology your kid will see in a freshman finance class — six years earlier, in a format they will actually read.

It Was Built For You.

what is inside

Twelve chapters. Same brain science the adults get. Zero condescension.

12 chapters
Real money science, kid language

One-to-one with the adult book Wired To Be Poor. Identity. Marshmallows. Opportunity cost. Compound interest. The 80/20 rule. NPV. Asset versus liability. Nothing dumbed down — just rewritten for a reader who deserves to be respected.

60+ diagrams
Hand-drawn. Pen-coloured. Designed to be argued with.

Multi-pen highlights in amber blue red green pink. Cursive margin notes that talk back to the main text. WHO SAID SO research cards. Pages built like the smartest kid in class took notes.

10 years of use
Built to be written in

A try-this prompt at the end of every chapter. White space left for the reader to argue back in pen. A glossary of every term, an index of every researcher. This is a workbook for the next decade of a reader’s financial life, not a once-and-shelved volume.

a peek inside

Pages that look like this.

Four figures pulled straight from the book. Hand-drawn, multi-pen, designed for a reader who learns by seeing.

Hand-drawn loop diagram with four nodes: MOTION, WINS, BELIEF, IDENTITY. Arrows around the loop labelled action, evidence, soaking in, more action.
Chapter 1 — identity is built outside-in
Hand-drawn seesaw with DEMAND tilted heavy on the left and SUPPLY light on the right. Caption: PRICE GOES UP.
Chapter 4 — how price actually happens
Three columns labelled ASSET, UTILITY, LIABILITY with examples listed underneath each and instructions: BUILD MORE, PAY THE MIN, CUT TODAY.
Chapter 7 — the three piles your stuff falls into
Hand-drawn chart over time with three lines: SPEND flat at zero, SAVE drifting up slowly, GROW curving steeply upward. Caption: today, same $20.
Chapter 6 — the curve school forgot to draw
who said so

Real researchers. Cited in-line. For kids who can handle it.

The book treats young readers as smart enough to meet the actual sources. A sample of the names a reader will meet, and the one-line reason each one matters.

marshmallow study
Walter Mischel

He let kids choose: one marshmallow now, or two in fifteen minutes. What they chose predicted everything.

self-perception theory
Daryl Bem

People learn who they are by watching their own behaviour. Motion first. Identity follows. Saying it never works.

the 80/20 rule
Vilfredo Pareto

In 1896 he noticed 80 percent of Italy’s land belonged to 20 percent of the families. The same curve runs your grades, your time, and your money.

ordinary wins
Bhattacharjee & Mogilner

Eight studies, 2014. Kids get more happiness from big peaks. Adults get more from the everyday. Useful early — it changes how a teen weighs the next "once in a lifetime" trip a brand is selling them.

harvard study of adult development
Waldinger & Holt-Lunstad

Eighty-five years of tracking real lives. The single biggest predictor of a long, healthy, wealthy life is not income. It is the quality of relationships. The book ends here for a reason.

the last line
James Clear

“You do not rise to the level of your goals. You fall to the level of your systems.” A teen who builds systems beats a teen who sets goals. The book closes on that.

Other names a reader will meet in the book include Kahneman, Thaler, Templeton, Ravikant, Munger, Damodaran, Maddux and Galinsky.

the core argument

You are not bad at money. You were never taught.

A 12-year-old sits in algebra learning x equals y and will graduate without ever being told the difference between an asset and a liability. They will sign a phone contract before they understand compound interest. They will be sold investments before they learn how a price differs from a value.

This is the book the system was supposed to give them. A reader who finishes it at twelve does not become a precocious finance kid — they become the kind of adult who never needs to fix their relationship with money later, because it was wired correctly the first time.

big idea
Identity is built outside-in. You do not become “good with money” by saying it in the mirror. You become it by doing the small things money-smart people do, watching the wins stack up, and letting belief catch up to behaviour.

The world does not pay for hours. It pays for the gap your work closes for someone who needs it closed. Wealth comes from owning things that work without you — not from trading more hours for a slightly higher rate.

The book makes this concrete with the reader’s own future in mind. Not a Charizard card metaphor in a textbook. A Charizard card example a kid actually owns.

this is the whole
game, actually.
for the parent

Why this book exists.

The financial system is the one thing nobody teaches kids. Schools do not. Most parents quietly cannot, because nobody taught them either. The result is a generation of adults who learn about compound interest after they sign the loan, and learn about opportunity cost after they spend the decade.

This is the book the system never gave you. A reader who finishes it at twelve does not become a precocious finance kid. They become the kind of adult who never needed to fix their relationship with money — because the relationship was wired correctly the first time.

Direct. Not preachy. Not condescending. Written with the same care a parent uses when explaining something important and only has one shot to get it right.

Written by Lakshya Behl, the guy who wrote the grown-up version. He didn’t dumb it down. He drew it out. — from the author of Wired to Be Poor
