I think Michael Jordan’s motivation started intrinsic and while he walked further on the way to a professional player he got more attention and so extrinsic motivation added on.
All of the sudden he felt succsess and that gave him even more motivation, power and strenght. I also belive after he felt the Athletic World is admiring him that gave him the motivation to go thru hard times in his career…..he wanted to be on top again.
P.s. By the way ….. I really like the training programm!!!!! 🙂
