I hate self help books, but this is completely different. It changed my life, recognising the thought processes at the start of the book was like someone switching on a light.
I hate those self help books which analyse why you do this that or the other, but this was totally different, focused, direct, and to the point. Doesn't dwell on why you are depressed etc, but tackles it with written exercises.
Cannot recommend it enough, it is a FANTASTIC, LIFE CHANGING book
