it may not seem a surprise to find out that less is more when it comes to managing creative type people. But now we have the research to back it up. Daniel Pink has done the research and is about to publish the book.
You can get a quick review of the idea in this article, or even better, watch him lay it all out on this video from the TED conference.
Pink is also the author of one of my favorite books of all time: " A Whole New Mind, or why right brainers will rule the Future." His new book, on motivation, is called "Drive, the surprising truth about what motivates us."
