I am a big collector of self help books but this one has probably influenced me more than any other.
Dr Phil is so straight to the point, without any jargon to confuse you. He gives you good examples from his own life and gives you good advice to complete the exercises. Once you have completed the exercises you will have a clear focus of who you are and why you think the way you do.
This book is simply brilliant, straight forward, easy to read and incredibly useful so if you feel you need to get your life together, this the best place to start
