Professor Nicholls is the best! This REBT course is so practical, I have found a vast use for it for my clients. This course of REBT not only extends the ABC model to F, but also includes a crucial part - the G or goal setting. One's REBT training is incomplete without this marvelous course! And Prof. Nicholls' teaching is incredibly effective! His beautiful way of explaining with examples, his enthusiastic voice, energetic body language are unforeseen! Lucky are his clients I can say!
