There is no question that Bruce Lee brought something new to film. He was not just a fighter. He was a master fighter and he depicted what mastery looked like. he was good at that too.
One of the ideas I like most from him is about focus. He built tremendous focus around what he was doing. How did he do it? Practice, of course. But not practicing a million things. Practicing one thing that he then mastered. To see that one thing, he believed in a “daily discard”. Discarding what was not essential each day. Nice idea!
