There is power in having passion and purpose, and in rediscovering them when things get tough. When Bruce Lee first began training, he studied Wing Chun under Ip Man in Hong Kong. But he didn’t complete the system because some students rejected him due to his mixed ancestry. Instead of letting that stop him, he went on to learn boxing for head movement and footwork, fencing for timing and distance, judo and jiu-jitsu for grappling, karate and taekwondo for precision kicking, Muay Thai and Savate for striking and clinch work, and Filipino martial arts like Kali (Silat), Eskrima, and Arnis for weapons and empty-hand techniques. He stayed loyal to the purpose, not the path. Passion kept him moving forward. That allowed him to create his own style of martial art, the Jeet Kune Do, or “The Way of the Intercepting Fist.” JKD was a philosophy of adaptability. In a 1971 interview with Pierre Berton, Bruce spoke about teaching martial arts to Hollywood actors like James Garner and Steve McQueen. When asked if he was teaching them acting, he said, “This might sound too philosophical, but it is unacting acting, or acting unacting.” Sometimes, you have to unlearn, to learn. Bruce believed that the most honest expression required both instinct and discipline. It is a balance, a harmony. Its about being real, in motion and in presence. He said, “Here, you have natural instinct. And here, you have control. You must combine the two in harmony. If you only have one in the extreme, you become unscientific. If you only have the other, you become mechanical. No longer a human being. So, it's a successful balance of both. Therefore, it's not just pure naturalness or pure unnaturalness. The ideal is unnatural naturalness or natural unnaturalness.” One of Bruce Lee's most powerful principles was: “Absorb what is useful, discard what is useless, and add what is uniquely your own.” In many ways that made JKD more of an open-source approach to martial arts rather than a structured and closed system. His thinking paved the way for modern mixed martial arts (MMA). But more than that, it became a philosophy of life.
