For every mistake that you learn from you will save thousands of similar mistakes in the future, so if you treat mistakes as learning opportunities that yield rapid improvements you should be excited by them. But if you treat them as bad things, you will make yourself and others miserable, and you won't grow.

The pain of problems is a call to find solutions rather than a reason for unhappiness and inaction, so it's silly, pointless, and harmful to be upset at the problems and choices that come at you (though it’s understandable).

We don't have ways of resolving the arguments in idea meritocratic way.

I think the basic problem is that everybody thinks they know what the truth is, and sometimes they're even distorting the truth to make their arguments.

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.

The best advice I can give you is to ask yourself what do you want, then ask 'what is true' - and then ask yourself 'what should be done about it.' I believe that if you do this you will move much faster towards what you want to get out of life than if you don't!
