I'd like to be clear that a number of people find me intolerable, and they don't hesitate to say so - which they and I cherish.

Know what your people are like, and make sure they do their jobs excellently.

To test if you are worrying too much about looking good, observe how you feel when you find out you've made a mistake or don't know something.

The meaningful work and the meaningful relationships are, to me, comparable rewards. I think being on a mission to do something great is great, and to be on that mission with people who you have really meaningful relationships with not only provides both types of rewards, but it's mutually supportive. Because you can have tough love, but there's also the love part of that in terms of the caring for each other, and when you have the caring you can be tougher on each other. Some people describe it as an intellectual Navy Seals.

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.

Watch out for people who think it's embarrassing not to know.

In order to get past disagreements, you just can't have one person with power decide. In other words, so just because I'm a boss, it would be terrible if I then said, "Okay, we're gonna go do this." That's why, after that thoughtful disagreement, there has to be a process of an idea meritocracy. That means okay, now you have to vote, not that the decision resides with power. And then you vote and move beyond it.
