I bought this book and audio as a New Years gift to myself 2016/2017. I listened to the audio 30+ times over the year. It is Grant's best product in my opinion. Simple, and to the point, and very very practical. I still listen to it every few weeks just to keep the information and re-enforce. Anyone who wants to achieve wealth, that's your book. I went from zero to 100K in 2017 using the information contained in this book (along with finding a business vehicle that allows me to do that, High Ticket Affiliate Marketing).
