A couple of good points, Gooch.
--It's not unlike what people do in other ways and in other programs. A comment I heard at a recent conference was that 'accepting the reality is the first part of changing.'
--Very few people master the concept in ten minutes. Usually when I've seen it described the presenter suggests trying it on something very simple such as frustration about not having any sharp pencils at work, being stuck in traffic, or your teenager leaving stuff around. Describe the emotion (C: frustrated, angry), describe the activating event in neutral terms (A: dirty laundry on the floor), and then identify the beliefs about that which are making you angry. Disputing them is almost always done by question/answer process.
The effective new beliefs can become something you find applicable to a wide range of situations ('I would prefer that the other drivers be more considerate and attentive, but it isn't worth getting angry about' can become 'It isn't worth getting angry about other peoples' behaviors').
