Always good to look at "How To" books with a healthy dose of skepticism. Probably more relevant to the "get rich quick" type books, because if they got rich quick, why would they be selling a book to give away their secrets?
Although I find things like farming and agriculture and outdoors to have a less capitalistic shade and more of a genuine "i want to help people achieve their goals and not die" shade.
