Self-awareness and self-discipline are both areas of interest for me. The first chapter of Stumbling On Happiness was a great read and expanded on both of these topics. Too many times have I done something so obviously detrimental to myself. I want to be able to control the disobedient elephant in my brain.
I'm not too sure what theory this would fall under, but I will definitely be reading more of Stumbling On Happiness. I also intend to check out the other books under the Illusion of Rationality category on the website.
