I am matching some quotes that I found on the web with my two conditions of creativity:
Sufficient condition of creativity
Alan Alda: The creative is the place where no one else has ever been. You have to leave the city of your comfort and go into the wilderness of your intuition. What you'll discover will be wonderful. What you'll discover is yourself. [Every journey starts with a first step, then a second step, then a third step. Keep on trying.]
Edward de Bono: It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
Linus Pauling: The best way to have a good idea is to have lots of ideas.
Ray Bradbury: Life is "trying things to see if they work."
A. A. Milne: One of the advantages of being disorderly is that one is constantly making exciting discoveries. [This is an excuse of being disorderly rather than fostering creativity. ;-)]
Albert Einstein: You can never solve a problem on the level on which it was created.
Peter Senge: New insights fail to get put into practice because they conflict with deeply held internal images of how the world works ... images that limit us to familiar ways of thinking and acting. That is why the discipline of managing mental models -- surfacing, testing, and improving our internal pictures of how the world works -- promises to be a major breakthrough for learning organizations.
William James: Genius means little more than the faculty of perceiving in an unhabitual way.
