his mind. the way his mind worked and the fact that he was SO open-minded. he truly was a free spirit. he took everything as it came and like he says on this quote he had NO limitations on himself. in other words, he was himself 100% of the time and didnt let people or society tell him what to think or what to do. he really didnt care about that. and that is yet another thing that makes him extraordinary, in my opinion. he was never trapped in that state of mind of thinking you have to be what everyone wants you to be and to hide your true self. he just WAS his true self all the time.
