A Little Book On Happiness is a concise collection of thoughts on how to change for the better. It is about learning to say no. A trip to the Emergency Room serves as a wake up call to the author. The book written in the days after that event is about focusing on what matters most in life. It is about clearing away the clutter in all areas of life and choosing and creating happiness. Short passages like "Catastrophe" examine what happens when things go wrong and end up better than if they had gone right.
