My response to this book was to remember the day I decided my default setting or response to life and the world was: I would be happy. Being happy was no longer something I would chase or work towards. I would simply be happy. My happy would no depend on any other person, event or thing. I was happy because I was happy. Since then, I have a very hard time keeping a bad mood. Being sad does not last. I find joy and contentment in all sorts of things. Only anger lasts for a while, but fades. My happy is constant.
