Do you make personal excuses?

I could not put this audible down! I highly recommend this book to anyone.
.
It really makes our personal excuses and things going on in our lives so insignificant compared to the struggles David Goggins went through… but more importantly, HOW he overcame them is where everyone could benefit in, even if just getting 10% of his mental toughness, the world would be so much better off. The ambition, goals, and not allowing himself to give up and tapping into the potential we dont even know thats possible for ourselves yet… 

<3 I feel like a major slacker in my mindset!

there is a lot of cussing in this book so not appropriate for my kids right now but they definitely will be reading this book when they get a bit older.

Have you read this book yet? is there a book (self-development) that you LOVE and was mind altering and life changing?
