Grant Cardone is the #1 international sales expert, also a successful author. I'm constantly following his YouTube channel and read his latest booklet which is the 'The Millionaire Booklet". The book itself doesn't cost anything, there is only a shipping price of $4.97 which is really nothing for the content of this booklet. It's an audiobook which 1:21 hour long. He discusses hwo to change your "avarage thinking" into financial thinking in 8 steps. For me it was very interesting and caught me thunking about these. Check it out if your interested in it too. https://grantcardone.idevaffiliate.com/859-7.html
