We must learn to suffer whatever we cannot avoid. Our life is composed, like the harmony of the world, of dischords as well as different tones, sweet and harsh, sharp and flat, soft and loud. If a musician liked only some of them, what could he sing? He has got to know how to use all of them and blend them together. So too must we with good and ill, which are of one substance with our life.
For studying courage in textbooks doesn’t make you any more courageous than eating cow meat makes you bovine. By some mysterious mental mechanism, people fail to realize that the principal thing you can learn from a professor is how to be a professor—and the chief thing you can learn from, say, a life coach or inspirational speaker is how to become a life coach or inspirational speaker. So remember that the heroes of history were not classicists and library rats, those people who live vicariously in their texts. They were people of deeds and had to be endowed with the spirit of risk taking.
Win through your actions, never through argument.
Any momentary triumph you think you have gained through argument is really a Pyrrhic victory: The resentment and ill will you stir up is stronger and lasts longer than any momentary change of opinion. It is much more powerful to get others to agree with you through your actions, without saying a word. Demonstrate, do not explicate.
