I finished read this book and it motivated me to make changes in my life. The way it's written is easy to understand and motivational at the same time. If you're a no nonsense person who like people to tell it to you straight, this will be a good read for you.
I read 75Hard as well, and this book is a good follow up. As a matter of fact, if you could only buy one, get this one. It can replace the 75Hard book as it contains the information from that book, and more information for the rest of the Live Hard program
