The book is ok.
At a glance, the book is very polarized. Corley paints an overtly negative portrayal of "bad habits" and an exaggerated picture of "rich habits". The image of rich habits is one of someone obsessed with success. Someone who structures one's life, in an orderly way with accountability, around succeeding in one's daily, monthly, yearly, and long term goals. Someone who maintains a few "30min/day" habits, counts one's calories, keeps his emotions on his leash, spends time every day off-work doing "self-improvement" for one's career, cuts spending and hobbies that aren't "constructive" (for one's career), etc. Basically a person obsessed with success.
It's not surprising that such an obsession with business success may lead to exactly that.
Reading between the lines, however, one sees the pendulum of human change.
Scoop up those struggling, down and out and push them too far in another direction, then let them swing back toward Slack, on and on to Human 2.0.
Taking the lighter perspective, one sees a general theme of consciously assigning energy to "the little things that matter". Little "bad habits" (you know what they are) add up; little "good habits" build up too.
Exercise is little, yet changes how one feels drastically.
Good food and sleep too.
Small calls/chats to keep up with people? (Don't do it much, but prolly does wonders).
Clarity on what you'd like to do and not (to help avoid vague feelings of dissatisfaction).
etc.
The bottomline advice: fix your little things.
