What matters most is that the people you work with share your values.

When people get at each other's throat, the rich and the poor and the Left and the Right and so on, and you have a basic breakdown, that becomes very threatening.

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

The main reason I write the daily observations is because I want to know where I'm wrong. So lots of times if somebody points something out it helps me, and I want to have a diversified bet of uncorrelated bets.

Don't worry about looking good - worry about achieving your goals.

Forget about what the technology is. Just understand the motivation behind it.

To have an idea meritocracy, one needs to do three things. First, they have to put their honest thoughts on the table, for everyone to look at and everyone to work through. Second, they need to have thoughtful disagreement, by which there are quality exchanges, in which there's open mindedness and the realization that no one has all the right answers. And you can work through that and get to better answers because good collective decision making is better than any individual decision making. And third, you have to have ways of getting past the disagreements if they remain.
