TED Talk: The puzzle of motivation

I watched Dan Pink talk about the puzzle of motivation. At first, he started with the problem of candle, how to stick candle on the wall. He said normally people can think the creativity solution when they in normal situation. On the other hand, if they have higher incentives, it will led to worse performance. Also he gave an example of reward. I agree with him because I have my own experience. I have designed any kind of  art work since I was in high school. I usually designed thing at night because it's really quiet and I don't have to work with the time. Although motivation will come with the under pressure situation.
