MJ’s source of motivation is intrinsic. He was competitive and he thrived on competition.
He loved and enjoyed what he did. Success would then naturally follow. He had a big heart and he took the bad together with the good that came with competition. When things were going his way he worked hard to stay top, when things did not go his way, he dug deeper.
His combination would be a type 3. He said he had not met anyone as competitive as he was.
Everything that he was, that made him who he was was from his love of the game. You have to enjoy what you do to last and stay top. If not, everything became a chore and no matter how motivated you are, you will never achieve the heights of elite athletes.
