Life is not an easy matter. You cannot live through it without falling into frustration and cynicism unless you have before you a great idea which raises you above personal misery, above weakness, above all kinds of perfidy and baseness.
A man who has never lost himself in a cause bigger than himself has missed one of life's mountaintop experiences. Only in losing himself does he find himself. Only then does he discover all the latent strengths he never knew he had and which otherwise would have remained dormant.
If you would win a man to your cause, first convince him that you are his sincere friend. Therein is a drop of honey that catches his heart, which, say what you will, is the great high-road to his reason, and which, when once gained, you will find but little trouble in convincing his judgment of the justice of your cause.
A good cause can become bad if we fight for it with means that are indiscriminately murderous. A bad cause can become good if enough people fight for it in a spirit of comradeship and self-sacrifice. In the end it is how you fight, as much as why you fight, that makes your cause good or bad.
