Perhaps these resources below in Life Management Resources or Psychology Resources, or even border on Philosophy Resources, but I thought you'd just read these to improve your life. So, these books are about success in life, what works, understanding your own psychology, formulating a philosophy that works, and /or using some life management principle in some varying combinations. If a book is +++, it is ranked as a must read.
+++You Can Have What You Want, Michael Neill - Very good on psychology of life, as he is a psychologist, yet also practical, as he is a high level coach. I'd also read his Feel Happy Now!, as it is also excellent.
