That's a big statement, I know, but David Goggins has such a unique, refreshing, and honest way of looking at things that unless you're intellectually and emotionally comatose (or would like to be), you can't help but grow as you read. After decades of conscious self-discovery I thought I knew myself well. Goggins showed me how I only knew the areas I wanted to know, and how the unexamined areas had been mud wrestling me behind the scenes for years. I'm going to come right out and say the one thing I never expected to say in a review: If in your life you're only going to read one book that will mess you up and set you right, you can't get better than this one.
