I'm extremely interested (read "obsessed") with creativity, innovation, and creative problem solving. People tend to hear the word "creativity" and associate it with artisitic pursuits (writing, painting, etc.). While artsitic expression is certainly an area of creativity it is simply one part of it. For example, there are many creative ways to solve problems (for both business and personal challenges).

I recently attended CPSI (pronounced "sip-see") where I learned creative problem solving methods, techniques, and activities. It was great! One keynote speaker was Dean Kamen, inventor of the Segway among many other things.
