Query: Can you use the internet?

If you can use the internet, you do not need this book. There are no "big secrets" or earth-shaking revelations here. The information presented in this book is free to anyone who can do an internet search on whatever subject they are interested in. The only thing I learned from this book is how to compile readily available information and sell it for a profit. SAVE YOUR MONEY!
