You must have complete determination. The worst opponent you can come across is one whose aim has become an obsession. For instance, if a man has decided that he is going to bite off your nose no matter what happens to him in the process, the chances are he will succeed in doing it. He may be severely beaten up, too, but that will not stop him from carrying out his objective. That is the real fighter.
Bruce LeeToo much horsing around with unrealistic stances and classic forms and rituals is just too artificial and mechanical, and doesn't really prepare the student for actual combat. A guy could get clobbered while getting into this classical mess. Classical methods like these, which I consider a form of paralysis, only solidify and constrain what was once fluid. Their practitioners are merely blindly rehearsing routines and stunts that will lead nowhere.
Bruce LeeI'm not in this world to live up to your expectations and you're not in this world to live up to mine.
