One of my favorite posts on the topic of Innovation-Killers, comes from the innovative blogsite, ThinkJar, created by Ben Weinlick. Ben attended The Intersection 2012 and has created a great site for convergent and divergent creativity. Take a look at this post on 21 Ways to Kill Creativity, written by Michael Michalko (author of Thinkertoys: A Handbook of Creative Thinking Techniques).
I would like to add one or two of my own creativity-killers:
1) don’t ever, ever, listen to your children’s ideas
2) immerse yourself in lots of television (especially sitcoms, game-shows, and reality tv series) and mobile games.
What other innovation-killers are you experience at home or work?
