You already know everything that is recommended here - get plenty of quality sleep, exercise, meditate, go for walks, have strong social relationships, be mindful, indulge in play, cultivate creativity and don't be afraid to be bored. But it feels good to have an expert tell you that you are on the right track, and it's always good to reinforce the things that you already know to learn them better and because all of us, no matter how saintly we may be, fall short of the ideal from time to time in every category and could do with a reminder. So I was glad I read it and felt I got something out of it, even though I didn't learn anything new.
