The martial arts are ultimately self-knowledge. A punch or a kick is not to knock the hell out of the guy in front, but to knock the hell out of your ego, your fear, or your hang-ups.
Bruce LeeYou will never learn anything new unless you are ready to accept yourself with your limitations. You must accept the fact that you are capable in some directions and limited in others, and you must develop your capabilities.
Bruce LeeInstead of dedicating your life to actualize a concept of what you should be like, actualize yourself.
