Here is the disclaimer self-help books should include:
“Following the advice in this book could make you millions of dollars and completely transform your life. On the other hand, it may not and you could hurt yourself in the process. So, regardless of the claim I just made – and the claims I made on the cover, back cover, and throughout this book – I make no claims. Use at your own risk. Don’t blame me or the publisher for anything bad that happens to you while trying to implement advice in this book. If things should work out well for you, please write a long 5 star review on Amazon and blog weekly about how my book alone made you millions and completely transformed your life (like I said it would, by the way).”
Funny but to the point honest!
