Showering, jogging, and listening to music follow as other inspiring situations. No one claimed to get great ideas in the office.
Every setting listed as the scene of creative inspiration involves fun or pleasure.
The ideal setting, then, is away from the workplace goofing off. Consistently creative people open their doors to all sorts of possibilities. The more possibilities they consider, the better their chances of letting in the wild idea that, combined with what they know and molded by their specific skills, makes an unmistakably breakthrough idea. In short, the creative process thrives on diverse and exotic stimulation. Which is why creative people need and seek stimulation.
