The first thing each morning, and the last thing each night, suggest to yourself specific ideas that you wish to embody in your character and personality. Address such suggestions to yourself, silently or aloud, until they are deeply impressed upon your mind.
After you've done a thing the same way for two years, look it over carefully. After five years, look at it with suspicion. And after ten years, throw it away and start all over.
How, then, find the courage for action?... By accepting the human condition more simply and candidly, by dreading troubles less, calculating less, hoping more.
