If knowing history made you rich, librarians would be billionaires.

Mr. Market is your servant, not your guide.

The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage.

More investment sins are probably committed by otherwise quite intelligent people because of "tax considerations" than from any other cause. One of my friends-a noted West Coast philosopher-maintains that a majority of life's errors are caused by forgetting what one is really trying to do. This is certainly the case when an emotionally supercharged element like taxes enters the picture (I have another friend-a noted East Coast philosopher who says it isn't the lack of representation he minds-it's the taxation).

I think you are out of your mind if you keep taking jobs that you don't like because you think it will look good on your resume. Isn't that a little like saving up sex for your old age?

You know ... you keep doing the same things and you keep getting the same result over and over again.

I would say that life at 84, I am having as much fun as I've ever had in my life. I mean I get to do what I love every day with the people I love-and it just doesn't get any better than that.
