Warren Buffett changed many schools while reading, but in the end, he chose Columbia University — that person was Graham.

Many people think he values the diploma itself. Actually, that's not the case. Buffett is not superstitious about academic credentials; he cares about one thing: who is right? Once he makes a decision, he shortens the distance by proximity. Not to get a prestigious background, but to hear the smartest people think every day.

This is the learning logic of top investors. Instead of spending four years in a highly ranked school in a daze, it's better to spend time sitting next to the right people. True skills are always learned.
