The friendship between these two men is incredible. Obviously the ideas explored are valuable and the practices at the end make it feel attainable. I do think, however, that there was a lot of repetition where deeper detail would be more useful. I enjoyed the story, I'm appreciative of their words, but I have to admit I wanted a bit more. I think this problem lies more with the editing. That being said, the "pillars" (as they refer to them) serve as fantastic goals to achieve better for yourself and others.
