The Compound Effect is a horrible book by a con artist called Dan Hardy. I looked him up and there is nothing about any business accomplishments, only that he wrote three books and was the publisher of Success Magazine, which has recently laid off some people and halted print.

This book was given to me by a guy that had a "business opportunity". I'm sure you have experienced this and I tell you, these books are where the real money is. These things are a scam, please share this or at least tell people that self-help books are full of BS.
