This is an excellent book. For some years I have taught tai chi to 50+ groups within adult education and the community and I wish I had had this guide when I started out. Paul Lam knows his tai chi and also considers carefully his clientele. There is a complete absence of the 'our method is best' mantra so often found in the tai chi world with its multiplicity of styles and 'masters'. Instead, Paul Lam gives sound guidance on how to prepare lessons, what to teach, how to consider the needs of your students, how to give them confidence and how to think about their health and also consider health and safety. His incremental teaching method is a masterpiece, I now use it with my students and their abilities have made a quantum leap. I can't wait until he teaches a UK workshop again so that I can meet the man in person. Meanwhile, this book is definitely worth buying.
