Back in 2001, Warren Buffett gave a talk at the University of Georgia and hit the students with the most Warren Buffett question ever:
“If you could invest in a friend and get 10% of their income for life, who would you choose?”
Classic Buffett, right? But then he flipped the script:
Once the students had their answers, he followed up with this:
- Why would you invest in that person?
- What character traits do they possess?
Now, suddenly, the students had a cheat sheet for success—a list of traits to adopt in their own lives.
But Buffett didn’t stop there. He asked a second question that really got the gears turning:
“If you could short a friend’s earnings—betting against them—who would you pick and why?”
Boom. Now they had a list of traits to avoid like the plague.
But here’s the kicker: this isn’t just about money. You can run this thought experiment with any kind of currency you value.
- Happiness Coin: If you could claim 10% of a friend’s happiness, who would you invest in and why? Who would you short?
- Fitness Coin: Who’s crushing it in the gym and who’s slacking off?
- Friendship Coin: Who’s the best friend you know, and who might be better left on the sidelines?
The brilliance of this exercise lies in its simplicity. It hacks a glitch in life’s video game: humans are often blind to their own flaws, but we’re experts at spotting them in others. If your friend is in a bad relationship, you can figure it out in 10 minutes—something that might take them 10 years to see.
And there’s one key nuance to remember: Buffett insists this exercise has to be based on merit, not luck. It’s not about picking someone because they’ll inherit a fortune; it’s about behavior, character, and choices.
This thought experiment is pure genius—a life hack straight from the Oracle of Omaha himself.
