The problem is how to remain an artist once he grows up. Imagination is more important than knowledge. There is nothing in a caterpillar that tells you it's going to be a butterfly. Restlessness and discontent are the first necessities of progress. Life is either a daring adventure or nothing at all.
Security is mostly a superstition.
It does not exist in nature. The only way to get rid of a temptation is to yield to it. Someone's sitting in the shade today because someone planted a tree a long time ago. I never married because I have three pets at home that answer the same purpose as a husband. I have a dog that growls every morning, a parrot that swears all afternoon, and a cat that comes home late at night.
