Grant Cardone is a business coach and motivational author and speaker.
Among Grant’s books you can find “The 10X Rule” which I find very useful and motivating. It’s a very good and useful book for entrepreneurs.
You also have The 10X Rule in audiobook version where Grant Cardone himself reads his book with his own voice. It’s just great! I love it! Been listening to it several times already and keep listening more and more because it’s motivating me to expand my business and to make more and more money!
