One of the greatest life lessons doesn't come from a business book.

It comes from Sonny in A Bronx Tale.

A friend owes the main character $20 and keeps avoiding him.

He asks Sonny what to do.

Sonny replies:

"It cost you 20 dollars to get rid of him. He's out of your life for 20 dollars. You got off cheap."

That advice goes far beyond money.

Some people will reveal their true character over the smallest amount.

They'll lie.
They'll disappear.
They'll betray your trust.

And all it cost you was $20.

Imagine discovering someone isn't trustworthy after investing years in a business, a friendship, or a relationship.

That would be far more expensive.

Sometimes losing a little money is actually buying valuable information.

Not every loss is a loss.

Sometimes it's the cheapest lesson you'll ever learn.

The real question isn't who owes you money.

It's who $20 revealed.
