Bruce Lee, The Man:
At the age of 13, Bruce started lessons in the Wing Chun style of Gung-Fu for the purpose of self-defense. Over the next 19 years, he transformed his knowledge into a science, an art, a philosophy, and a way a life. He trained his body through exercise and practice; he trained his mind through reading and reflecting, and he recorded his thoughts and ideas constantly over the 19 years.
Bruce Lee's Quest:
In his life-long search for self-knowledge and personal expression, Bruce was constantly studying, analyzing and modifying all availible relative information; his principle source was his personal library which consisted of over 2,000 books dealing with all forms of physical conditioning, martial arts, fighting techniques, defenses and related subjects.
The Tao of Jeet Kune Do:
The Tao of Jeet Kune Do actually began before Bruce was born. The classical Wing Chun style that started him on his way was developed 400 years before his time. The 2,000 or so books he owned and the countless books he read, described the individual discoveries of thousands of men before him.
