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

I don't think there is such a thing as the perfect system.

For me, the best things in life - meaningful work, meaningful relationships, interesting experiences, good food, sleep, music, ideas, sex, and other basic needs and pleasures - are not, past a certain point, materially improved upon by having a lot of money.

It is a law of nature that you must do difficult things to gain strength and power. As with working out, after a while you make the connection between doing difficult things and the benefits you get from doing them, and you come to look forward to doing these difficult things.

If you can stare hard at your problems, they almost always shrink or disappear, because you almost always find a better way of dealing with them than if you don't face them head on. The more difficult the problem, the more important it is that you stare at it and deal with it.

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

Over time, it also became important for me to share my management principles with the people I worked with because we had to agree on how we should be with each other - and that way is unique. Because the logic behind being radically honest and radically transparent with each other wasn't clear, it had to be spelled out in these principles.
