In the years that I have known Colin, I have come to realize the depth of his dedication to learning the martial arts and to passing along his knowledge to others. So, it is no surprise that his personality and ability to teach come through in this book. This makes his book both informative and enjoyable to read, with content that is easy to digest, despite its complexities.
