Because of their courage, their lack of fear, they (creative people) are willing to make silly mistakes. The truly creative person is one who can think crazy; such a person knows full well that many of his great ideas will prove to be worthless. The creative person is flexible -- he is able to change as the situation changes, to break habits, to face indecision and changes in conditions without undue stress. He is not threatened by the unexpected as rigid, inflexible people are.
