⭐⭐⭐⭐ out of 5
This is a good basics read, but the author expects you to already have a product to sell, a mailing list or a database of people to sell it to.
Tough luck if, like me, you have neither.
It took a while to get started and I've got a list of new things to try now, but I'm no further towards making money than I was when I started reading it.
It's a good read but you already need to have something to work with to really benefit from it.
If all you've got is an idea for something you want to make money from then look elsewhere. If you can't afford to spend money, look elsewhere. If you're willing to waste 30 days of your life to gain very little from it, this is the book for you.
It seemed to be mainly the author promoting his website and using businesses like Amazon and Apple to prove a point.
If you've already got the basics sorted and you want to take the next step but don't know how, this book might help you, but if all you've got is an idea then you'll be sorely disappointed unfortunately.
