It takes considerable knowledge just to realize the extent of your own ignorance. Most of us have gears we never use. Each friend represents a world in us, a world possibly not born until they arrive. Opportunities are like sunrises. If you wait too long, you miss them.
Dreams are extremely important.
You can't do it unless you imagine it. If you're going to create, create a lot. Creativity is not like playing the slot machines, where failure to win means you go home broke. In human endeavor, chance favors the prepared mind.
