Question
I've read many money-making books, only to find that the author makes a lot of money when a lot of people buy his book. My question is, how can I tell that a book is really giving out helpful/useful money-making knowledge or just a means to make money for the author?
Answer
Just stop reading those books. Get to work, get your hands dirty, and figure out first-hand how to be more efficient and effective.
If you read, then consider studying a new skill that can be put to use. Reading about making money won't help you succeed any more than watching porn will get you a date.
