Scott Berkun, author of The Myths of Innovation:
I teach a creative thinking course at the University of Washington, and the foundation is that ideas are combinations of other ideas. People who earn the label “creative†are really just people who come up with more combinations of ideas, find interesting ones faster, and are willing to try them out. The problem is most schools and organizations train us out of the habits.
Another source of idea is the future. If the mind could reverse its psychological arrow of time for a brief moment, it would be able to remember its own future, instead of its past. I would be willing to say more, but it’s Mike Linksvayer Day today, and he will come here to post a sarcastic comment ridiculing my concept of precognition, so I will save my thoughts for another day, when that radical San Franciscan is in a better mood to listen to some mutant theory.
