I'm scared of people with power making the decision.

Life is like a giant smorgasbord of more delicious alternatives than you can ever hope to taste. So you have to reject having some things you want in order to get other things you want more.

Constantly probe the people who report to you, and encourage them to probe you.

Everyone has to decide for themselves what works for them and their organization.

I'm sure Donald Trump will think that he has the truth, and some journalist is arguing that he has truth, and somebody else is arguing that they have the truth. And in fact it's even worse than that because they're so hell bent on their arguments that they will distort the truth consciously. They'll manipulate the facts to support their arguments because they're so hung up in the fight. That's where the problem is, so we argue all the time.

I believe that one of the best ways of getting at truth is reflecting with others who have opposing views and who share your interest in finding the truth rather than being proven right

The biggest mistake investors make is to believe that what happened in the recent past is likely to persist. They assume that something that was a good investment in the recent past is still a good investment. Typically, high past returns simply imply that an asset has become more expensive and is a poorer, not better, investment.
