Those who matter don't mind, and those who mind don't matter.

Approach each new problem not with a view of finding what you hope will be there, but to get the truth, the realities that must be grappled with. You may not like what you find. In that case you are entitled to try to change it. But do not deceive yourself as to what you do find to be the facts of the situation.

Making a success of the job at hand is the best step toward the kind you want.

Get to know yourself. Know your own failings, passions, and prejudices so you can separate them from what you see. Know also when you actually have thought through to the nature of the thing with which you are dealing and when you are not thinking at all... Knowing yourself and knowing the facts, you can judge whether you can change the situation so it is more to your liking. If you cannot--or if you do not know how to improve on things--then discipline yourself to the adjustments that will be necessary.

I'll give you the bottom 10% and the top 10% of any move if I get to keep the middle 80%.

Old books that have ceased to be of service should no more be abandoned than should old friends who have ceased to give pleasure.

Become more humble as the market goes your way.
