Neurolinguistic Programming 
I first encountered NLP in 1985 when my Indian friend, Nanda Kumar, came to me all excited. "I've just had the most amazing experience of my life!" he exclaimed. During the five years I had known Nanda, he'd had some pretty incredible adventures, so he definitely had my attention. He went on to describe a "firewalk seminar" he had attended in California and wanted to bring -- lock, stock, and charcoal pit -- to Japan. Would I help him?
I intend to write a lot more about NLP here soon, about how I came to own a company that specialized in NLP training, how I eventually became a certified NLP practitioner, and why NLP has become an important part of my life. I'd also like to include LOTS of links to the sites of my NLP colleagues, such as Robert Dilts, John Seymour, Joseph O'Connor, more, more, more. For the moment, if you wish to explore a bit in your own, there is a good starting point at NLP Resources. And for those who have been seeking a simple definition of this incredibly powerful behavioral science, here's my favorite: "NLP is the study of how what we do and say relates to what we think." Is there anything else worth studying?
