If you don't own Gold, you know neither history nor economics.

The expression I use: Pain + Reality = Progress. Whenever I would have a painful mistake, I started to view that as puzzles that would give me gems if I could solve the puzzle. So, it made me thoughtful - what should I do differently next time? That was the puzzle. And the gem was some principle for handling the same thing when it came along again, and then I would write it down. And by writing it down and referring to it, and also being able to show it to other people so that we could agree that that was a good way of handling that thing - that was very, very powerful.

There is nothing to fear from truth....Being truthful is essential to being an independent thinker and obtaining greater understanding of what is right.

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.

Principles are concepts that can be applied over and over again in similar circumstances as distinct from narrow answers to specific questions. Every game has principles that successful players master to achieve winning results. So does life. Principles are ways of successfully dealing with the laws of nature or the laws of life. Those who understand more of them and understand them well know how to interact with the world more effectively than those who know fewer of them or know them less well.

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.

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.
