Distinguish open-minded people from closed-minded people. Open-minded people seek to learn by asking questions; they realize that what they know is little in relation to what there is to know and recognize that they might be wrong. Closed-minded people always tell you what they know, even if they know hardly anything about the subject being discussed. They are typically made uncomfortable by being around those who know a lot more about a subject, unlike open-minded people who are thrilled by such company.

When I say I believe in radical truth and radical transparency, all I mean is we take things that ordinarily people would hide, and we put them on the table, particularly mistakes, problems, and weaknesses. We put those on the table, and we look at them together. We don't hide them.

Sometimes we forge our own principles and sometimes we accept others' principles, or holistic packages of principles, such as religion and legal systems. While it isn't necessarily a bad thing to use others' principles - it's difficult to come up with your own, and often much wisdom has gone into those already created - adopting pre-packaged principles without much thought exposes you to the risk of inconsistency with your true values.

Remember that experience creates internalization. Doing things repeatedly leads to internalization, which produces a quality of understanding that is generally vastly superior to intellectualized learning.

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.

Never say anything about a person you wouldn't say to them directly, and don't try people without accusing them to their face. Badmouthing people behind their backs shows a serious lack of integrity and is counterproductive. It doesn't yield any beneficial change, and it subverts both the people you are badmouthing and the environment as a whole.

People who acquire things beyond their usefulness not only will derive little or no marginal gains from these acquisitions, but they also will experience negative consequences, as with any form of gluttony.
