Can’t Hurt Me by David Goggins is pretty great. Every time I think something is hard, especially while working out, I think if this book and this lunatic. Dude was a Seal, a Ranger, and whatever the Air Force equivalent. Had a weird/terrible life up to that point where he says he finally realized his limits were all in his head. Just an amazing and inspiring human being. He’s also a pretty great Twitter follow even though he rarely posts. Stay hard mother fuckers!!!
Also, after you read that you can read Living with a Seal. A rich dude paid Goggins to live with him for a month. He had to do everything he said for the month. It’s def more LOL than the above and is a quicker read. You can actually read this first but I think it makes it better knowing Goggins more after reading his book first.
