One of my all-time favorite teacher/philosophers, Bruce Lee demonstrated the curiosity of on-going self discovery mixed with the power of collecting knowledge to synthesize it into something fresh and practical.
Listen to Shannon Lee teach her father's philosophy. She obviously loved him a great deal and has worked to preserve his legacy and his teachings.
Be Water, My Friend: The Teachings of Bruce Lee
If you haven't watched Enter the Dragon, you haven't been properly introduced to Lee. My favorite seen in this quintessential film is where Bruce Lee teaches the art of fighting without fighting.
