I think I am rapidly gaining a reputation for bein' something of a smart alec, but in all seriousness, the Infinate Insights' books are almost literally the Gospel fer Kenpo folk. They are tremendously well written and offer insights into the core philosphies and concepts which our art is based upon. Most definately a MUST READ for anyone involved in Kenpo.
I would also highly recommend Lee Wedlake's books, Kenpo Karate 101 and Kenpo Karate 202. As these have some great ideas as well.
Good luck on your journey and hope you find your own answers along the way.
(Lookee!!! I almost made an entire post without any flippant remarks! See? I CAN do it.)
