Two words: Handbook and Formula. This seems to be a no-nonsense, pure with no fluff (like you see in many books like this), guidebook for those who want to improve their frustrations on life and improve their outlook on life.
I would choose this book because of this, and the book cover is simple and no-nonsense as well, which I like. Clear and simple.
