Fun video!  It mentions autonomy and purpose.... when those are tied together as a feeling of personal empowerment in the pursuit of your own values and values you agree with, it is self-interest and self-esteem and integrity... and it is easy to see how the enjoyment of mastery arises during that pursuit.

Interesting.  I found books by Daniel Pink at the library. I put Drive and To Sell is Human on hold.  I also found his website: www.danpink.com

I am interested in finding the initial studies from MIT, the FRB, etc.  The book, Drive, should lead to those.  

He presents the same ideas with different words on this TED:Oxford Talk.

Thinking about this while watching that...  It might be said that Peter Keating (following his mother's teaching) saw architecture as a repetitive skill for which material incentives matter and material rewards measure outcome. For Howard Roark, architecture was a "candle problem," an exercise in creativity. That could be widened to the conflict in Atlas Shrugged as a consequence of the two opposing value systems of the heroes and the looters.
