It's really clear to me that you can't hang onto something longer than its time. Ideas lose certain freshness, ideas have a shelf life, and sometimes they have to be replaced by other ideas.

Laugh at yourself, but don't ever aim your doubt at yourself. Be bold. When you embark for strange places, don't leave any of yourself safely on shore. Have the nerve to go into unexplored territory.

You can't get there by bus, only by hard work and risk and by not quite knowing what you're doing. You have to leave the city of your comfort and go into the wilderness of your intuition. What you'll discover will be wonderful. What you'll discover will be yourself.
