Instead of going back into the past to analyze which childhood traumas have caused low self-esteem and dysfunctional relationships, this book deals with the present - what we think and feel on a day-to-day basis. Richard Carlson shows the reader that the thoughts we generate in turn create feelings and that we can direct our thoughts in any direction we wish - we needn't be slaves to negativity, angst or sadness. Everyone experiences mood changes, but it is important to remember that the thoughts we have while in a low mood are not to be trusted.
