The key to most difficulties does not lie in the dilemmas themselves, but in our relationship to them.

Tell a man something is bad, and he's not at all sure he wants to give it up. Describe it as stupid, and he knows it's the better part of caution to listen.

No man will work for your interests unless they are his.

Courage and conviction are powerful weapons against an enemy who depends only on fists or guns. Animals know when you are afraid; a coward knows when you are not.

He who doesn't consider himself is seldom considerate of others.

Enthusiasm is the best protection in any situation. Wholeheartedness is contagious. Give yourself, if you wish to get others.

Intellectual comradeship requires that you think your thoughts through to the place where you can make the complex seem simple, the obscure quite clear.
