Jim, I'm usually a bit skeptical about these courses, perhaps in a complacent or sour grapes way because I was never fortunate enough to go on one myself. But in a coincidence too silly to be ignored, the first envelope I tore open after reading the forum and deciding to attempt some half hearted work, contained advertising from a body called the Principals' Training Centre who are running six courses this June/July in apparently relevant areas. Trouble is, they are in Miami and London, not places to which you can thumb a lift from Bangkok. They are at www.ThePTC.org, and might be worth checking out: I have no other knowledge of them, and receive no commission. Good luck.
