Just so you guys know, when you see links to Amazon for books I recommend? They're usually affiliate links. In other words, if you follow the link and buy the book I make a little money. (Not much, but a little.)
Does that mean I'm recommending a book just to make money? No. I link to books because it makes it easier for you to find exactly the book I'm talking about. The fact that I might make a little fee if you buy it via my link is just a bonus.
