When dealing with people, let us remember that we are not dealing with creatures of logic. We are dealing with creatures of emotion, creatures bristling with prejudices and motivated by pride and vanity. ...Any fool can criticize, condemn, and complain - and most fools do. But it takes character and self-control to be understanding and forgiving.

The most important thing in life is not simply to capitalize on your gains. Any fool can do that. The important thing is to profit from your losses. That requires intelligence, and makes the difference between a man of sense and a fool.

The difference between a grave and a rut are the dimensions.

First ask yourself: What is the worst that can happen? Then prepare to accept it. Then proceed to improve on the worst.

When we are not engaged in thinking about some definite problem, we usually spend about 95 percent of our time thinking about ourselves. Now, if we stop thinking about ourselves for a while and begin to think of the other person's good points, we won't have to resort to flattery so cheap and false that it can be spotted almost before it is out of the mouth.

Criticisms are like homing pigeons. They always return home.

So, to prevent fatigue and worry, the first rule is: Rest often. Rest before you get tired.
