very interesting stuff. I've read very similar material - but in an education context. Maria Montessori's philosophy of education from early 1900s is based entirely on intrinsic motivation of the child: to learn to love learning, to do it because its fun, to do it because it matters, to strive and achieve your potential (your potential, not your classmates), to have an inner drive and purpose. in other words, the student learns to do his best because of his own inner desire and motivation, not because he wants praise or good grades or other external rewards.
not to say external rewards are not important. they are. but self-satisfaction in your performance (at school and work) is what matters most.
if you see a good montessori classroom in action you will observe children managing their own work plans every day, managing their time, with some decisions to make like which work comes first, second, etc., mastering one level in a particular work and then proceeding to the next level (wow, I finally get to do this planet work I've been waiting so long to do!) with a lesson from the teacher, giving a younger child a lesson on a subject he has previously mastered, etc. that child has autonomy (within structure). and feels a sense of purpose. and at the end of the work period, 3 or so hours later, the child feels glad in his heart that he was able to achieve his work for the day. his performance is not tied to others in the class, though the children do frequently work together. his performance does not gain him anything really - he doesn't get an A for the day or a star on a chart. because his performance belongs to him. the sense of achievement is what makes him happy.
this guy definitely has it right. its nothing new. the business world (and schools) could definitely benefit from this kind of thinking.
