Ask yourself whether you have earned the right to have an opinion. Opinions are easy to produce, so bad ones abound. Knowing that you don't know something is nearly as valuable as knowing it. The worst situation is thinking you know something when you don't.

Radical transparency fosters goodness in so many ways for the same reasons that bad things are more likely to take place behind closed doors.

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.

I believe there are an infinite number of laws of the universe and that all progress or dreams achieved come from operating in a way that's consistent with them. These laws and the principles of how to operate in harmony with them have always existed. We were given these laws by nature. Man didn't and can't make them up. He can only hope to understand them and use them to get what he wants.

The most important thing you can have is a good strategic asset allocation mix. So, what the investor needs to do is have a balanced, structured portfolio – a portfolio that does well in different environments…. we don't know that we're going to win. We have to have diversified bets.

Success is achieved by people who deeply understand reality and know how to use it to get what they want. The converse is also true: idealists who are not well-grounded in reality create problems, not progress.
