I wonder if no matter what it is you wish to learn to be or how to be it you can find a book on it?

How to knit
How to crochet
How to fish
How to swim

How to hate
How to murder
How to torture
How to cruel your way in life
How to win at any cost in any way for any reason at any time

I expect there are "best" and "less best" ways to hate. What makes hate more effective or less?

Certainly experts would share their secrets if the price is right.
