This is one that personally self-discipline is something that I've personally struggled with for a long time. It made me kind of realize how many like little bad habits that I have here and there. But at the same time to kind of go back to Benjamin Franklin's quote about searching for vices, it made me want to change my ways. To me, this is an easy 5.0 book. I love the way he tells the stories. He's got a lot of depth here without being superfluous on many things. So I feel like it's well put together.
