The core idea
My wealth has come from a combination of living in America, some lucky genes, and compound interest.
— Warren Buffett, age 95
What is compounding?
Compounding is when your returns earn returns. You grow not just on what you put in — but on every gain before it. The longer it runs, the faster it accelerates. Time is the real multiplier.

The longer the hill, the bigger the snowball. Buffett's net worth grew slowly — then explosively.
His journey
Age 11
First stock purchase. Bought 3 shares of Cities Service. Sold early, then watched it climb. Lesson: patience beats timing.
Age 26
Launched his first partnership. Started with $105,100 from family and friends. The snowball found its hill.
Age 56
Net worth ~$1.4 billion. Already enormously successful — but only a fraction of what was to come.
Age 65+
The compounding explosion. The vast majority of his fortune was built after this point. Decades of returns compounding on returns.

What you can do
1
Start as early as possible
Even small amounts invested early have decades to compound. Time matters more than the size of your initial investment.
2
Invest consistently
Don't wait for the "perfect" moment. Regular investing beats trying to time the market — Buffett learned this at age 11.
3
Stay invested — always
The multiplier is time. Every year you stay invested, your gains start earning gains. Stopping breaks the snowball.
4
Automate and anchor your "why"
Automate contributions so discipline doesn't rely on motivation. Tie it to a goal — freedom, a home, security — to stay the course.

Warren Buffett didn't get rich fast.
He got rich for a long time.
The lesson isn't about genius. It's about time.
