Creativity is paradoxical. To create, a person must have knowledge but forget the knowledge, must see unexpected connections in things but not have a mental disorder, must work hard but spend time doing nothing as information incubates, must create many ideas yet most of them are useless, must look at the same thing as everyone else, yet see something different, must desire success but embrace failure, must be persistent but not stubborn, and must listen to experts but know how to disregard them.
