Applying UL lessons to life — suggested reading?

One of the things I enjoyed most about rereading Ray Jardine's Beyond Backpacking is the undertone that UL principles carry over into everyday life. Doing more with less on the trail leads me to think of ways to simplify other areas of life. I just turned 45 and there's a lot of junk — physical, financial, and Karmic — I could jettison.

Anyone have reading suggestions/comments along these lines?
