Tao of Jeet Kune Do by Bruce Lee. Not actually reading it front to back, but rather skimming through since it was just a compilation of his notes and piecework for the book he was working on. Actually, this is the fifth time I've went through the book just for reference, and to see if I can draw yet another meaning from the book's tidbits of practical advice and philosophy as my training progresses.
At this very moment I am reading "The Making Of a Martial Artist", by Dr. Sang Kyu Shim. It is a brilliant book. more of a philosophical approach. It does not address techniques, but the actual martial artists and their progression and development.
I have not read any martial arts books latey since I moved for college all most ever ma book i left at my parents home but I am looking for one now so if you guys and girls see any on sport karate plese let me know cause I am starting to focus more on that
