Here's one truth that perhaps your typical investment counselor would disagree with: if you're comfortably rich and someone else is getting richer faster than you by, for example, investing in risky stocks, so what?! Someone will always be getting richer faster than you. This is not a tragedy.

All intelligent investing is value investing - acquiring more that you are paying for. You must value the business in order to value the stock.

Although I am very interested in the subject of human misjudgment - and lord knows I've created a good bit of it - I don't think I've created my full statistical share, and I think that one of the reasons was I tried to do something about this terrible ignorance I left the Harvard Law School with.

For some odd reason, I had an early and extreme multidisciplinary cast of mind. I couldn't stand reaching for a small idea in my own discipline when there was a big idea right over the fence in somebody else's discipline. So I just grabbed in all directions for the big ideas that would really work.

Understanding how to be a good investor makes you a better business manager and vice versa.

We all are learning, modifying, or destroying ideas all the time. Rapid destruction of your ideas when the time is right is one of the most valuable qualities you can acquire. You must force yourself to consider arguments on the other side.

There is bound to be a regression toward the mean.
