Listened to it's audiobook version. Outstanding book with a story which says that pretty much every limit, especially in the physical realm, can be beaten, no matter your starting position. David Goggins is like a case when I imagine - what can be possible if you start living in 100% mode without any excuses... And to think that this story is ACTUALLY real, that it was done in real life by someone with really bad starting position - makes you think and re-prioritize your life a lot.
Went for a 30 minute run yesterday which was my longest run after more than 5 years because of the book and will make it a long-term habit.
