In prison, a guy asked me to help him calculate how rich he’d be once he got out.
We ran the numbers. Perfect assumptions. Perfect returns.
I slid the paper back and said, “Your calculator works. Your habits don’t.”
He looked confused.
“Math doesn’t fail people,” I said. “People fail math.”
He stopped asking about returns. Started asking about discipline.
Lesson: The math is easy. The behavior is brutal.
That’s why so few win.
