Borrowed from a post by calliope on The Arcadian Bookroom:
Ulrich Kraft, who writes for Scientific American, says the steps to having a creative mind are as follows:
1. Wonderment. Try to retain a spirit of discovery, a childlike curiosity about the world. And question understandings that others consider obvious.
2. Motivation. As soon as a spark of interest arises in something, follow it.
3. Intellectual Courage. Strive to think outside accepted principles and habitual perspective such as "We've always done it that way."
4. Relaxation. Take the time to daydream and ponder, because that is often when the best ideas arise. Look for ways to relax and consciously put them into practice.
