For me, I would think that the most valuable bits are in the Photo Editor's post, especially the following,
"8. Eliminate excess Drama from your life.
9. Live beneath your means. Keep things simple.
20. Travel out of the country as much as possible. Learn how other people live. Learn that America is not the center of the universe, and learn that you don’t need your cell phone 24 hours a day. Again, be a sponge, about how other people live."
