Every 'How To' book ever

Yep:

As a person with a bit of art about me, I chuckle at the "How to Draw" books you can purchase.  They often look like this.  Same with "How to learn piano."  They're basically like a book that says 'How to fix an automatic transmission if four easy steps.  Step one: Remove the engine.' 

Most 'How to books" could save trees and paper by saying the same thing: How to?  Hard work, lots of practice and lots of trial and error.
