Dan Pink : The puzzle of motivation

This was a very nostalgic story. When I started studying English, I read this.

Dan Pink at TEDGlobal 2009
The puzzle of motivation  (transcript)
Summary
There might be many people who don't agree with this story because they think that they definitely do better when they get more salary. However, this way that means to use carrot and sticks called if-then rewards. It works only in very narrow circumstances 1) but it often destroys creativity.2) Yes, people don't hit upon a good idea when they get money. It's a bad idea, you know, it's often used in your companies, though.

In fact, the secret to high performance isn't rewards and punishment and it's unseen intrinsic drive that is to do things for your own sake. The drive to do things cause you matter. The true motivation comes from autonomy, mastery, and purpose. You must know and have it and don't be puzzled by others.
