Dr Carlson has written many self-help books aimed at helping us to find the stable state of happiness that naturally exists within us all. He has now written this book specifically for those of us who suffer from depression. The book contains practical truths that are so obvious that most of us miss them or at least bypass them in the rush of our everyday lives. If you are suffering from depression this book will help immensely. Richard Carlson will show you how your state of depression is as much perpetuated by your own thinking as it is by any chemical imbalance that may or may not exist. I have read this book at the same time as receiving treatment with an SSRI anti-depressant (Cipralex). While I am unsure if the SSRI has benefited me at all after 6 weeks, I am certain that this book has changed my outlook completely after two weeks and that it continues to do so more and more with each re-reading. If I allow myself to slip back into my old ways of thinking, the severity of my depression rapidly returns. The good news is that it just as rapidly alleviates when I get back on track with my thinking. Another reviewer has said that the book is repetitious and simple to read and yet that Dr Carlson's approach is hard work to put into practice. I both agree and disagree with this view. The book is simple to read and may seem repetitious. However, if you are one of Dr Carlson's target audience of sufferers from depression you should read this book and keep on re-reading it. You will find that on each re-reading something will leap out at you with greater meaning than it did before. I have highlighted many sentences so that I can rapidly re-read them, and have noted down the keywords on the title page. This way I can pull myself back on track quickly. I also agree that the approach takes some work to put into practice but I think the previous reviewer misses the point that there is nothing as hard work as being in a depressed state. The hard work, by the way, is only in terms of changing your habitual modes of thinking, it does not involve making lists and analysing things as do many cognitive (i.e. thinking) approaches such as that found in Feeling Good: The New Mood Therapy by David Burns. I have found Dr Burns's book to be of some use also, but only in so far as it enabled me to identify particular types of cognitive distortion that help perpetuate depressive illness. This enables me to more accurately recognise when I should dismiss my thoughts, as Dr Carlson recommends in his approach. If you are depressed, low, angry, resentful, dissatisfied, unfulfilled, stressed, hurried, fearful or just not happy most of the time then read this book and keep re-reading it. I only wish this book had been available when I was aged twenty rather than forty.
