I believe that our society's "mistake-phobia" is crippling, a problem that begins in most elementary schools, where we learn to learn what we are taught rather than to form our own goals and to figure out how to achieve them. We are fed with facts and tested and those who make the fewest mistakes are considered to be the smart ones, so we learn that it is embarrassing to not know and to make mistakes. Our education system spends virtually no time on how to learn from mistakes, yet this is critical to real learning.

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

I do think people need to recognize that a lot of journalists want to write a story a certain way because the story will be better or the portrayal will be better, or at least recognize that whenever you're looking at something, you're seeing it through somebody's eyes who may actually not be the person who is the most insightful.

In return, society rewards those who give it what it wants. That is why how much money people have earned is a rough measure of how much they gave society what it wanted.

To make money in the markets, you have to think independently and be humble.

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.

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