Almost unbelievable life story of David Goggins is captivating. He proves that people are capable of incredible things. E.g. going through the Navy seals hell week with injured knee. Like, really? He is sometimes just too extreme for a human, but his story is truly inspirational. He has a lot to tell and thus the book was very entertaining for me.
I don’t know if it is a coincidence, but 5 days after finishing the book I broke my own record in running. :)
