I think MJ’s motivation is a mix of both. His self-belief in himself, the game and his willingness to seek greater heights. He mentioned he can fail but he will work to overcome the obstacles. Very clear in this area. Winning awards are just indicators or checkpoints telling him or reassures him what he is doing and keep him going.
Personal values, at least in the game of basketball, he constantly seeks new heights. His love and and passion for the game and is true to it regardless what happens. Be it he had a bad day or constant victory, he strive to better himself.
Clearly, he seems very clear a type 3 in my opinion.
