Honestly, good luck to him but it's just self-help "look at me I live an ascetic life of discipline" blah blah. In my mind, it is a little hard to take. "Here's my algorithm: by waking up early, I have two spare hours at lunch to help 2 people, at a rate of 1 per hour then I go to bed and early promptly but not before my nightly stroll about town." Follow this routine strictly for 20 years and let me know how that works for you.
