I highly recommend this book - just finished it.
I could give you the highlights and main points, but I think, like everything, "if you really want to make a change, you will make the effort and do it". This book is inspiring and will help you get motivated to understand your bad habits and help start good ones. I tell clients all the time, I can only help you if you are ready to want help. Then it's easy from there. You've got this!
