I want to begin this post by telling you what I look for in a good self-help book. There have been many books that I've started and decided, usually after giving it a really good go, that they aren't for me. I don't like books that ask me to believe in things that are illogical. I don't like books that attempt to inspire me. I allow a certain amount of airy-fairy nonsense into my life as long as it is self-aware nonsense. I think one can certainly be too rigid in their beliefs because facts can change when more evidence is gathered. But there's a line. Here are three books that I really enjoyed, that helped me see the world differently and didn't cross that line.
