How the mind creates ideas

More from Michael Michalko in Psychology Today
"When you are brainstorming for ideas and have a thought, the value of that thought depends upon how you interact with it. We are educated to be critical, judgmental, logical thinkers and to instantly evaluate and judge thoughts based on our past experiences. If there is any ambiguity, the judgment is invariably negative and the thought dissipates back into nothingness. The ordinary mind has no tolerance for ambiguity because it is conditioned to simplify the complexities of life."
