This book changed my life. Although the title talks about fueling successes and performance at work, I believe this material has universal applicability. Everyone should read it! I began doing the daily exercises as soon as I finished the book, and felt myself gradually adopting a more positive outlook over the next couple of weeks. My biggest take away from the book is to focus my energies on the things I am able to control in my life and avoid worrying about what I cannot control.
