I'm not a big fan of self help books so this is really bias. I don't like self help books because it's full of capitalist ideology and I'm not interested in that lifestyle. I was recommended this book so I said why not. One big thing I disliked is the left brain vs right brain, I know this was written in 1989 so it can not be taken out but that myth is false. There's no such thing. I like some of the habits but I'll incorporate it in my life in a way.
