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.
