There's an interesting site I stumbled across called zenhabits, whose focus is "simple productivity." They've got some interesting articles on decluttering your life, slowing down to enjoy the roses, and doing less to be more productive (very zen, that last).
The blog is run by Leo Babtauta, a Guam-based writer. It has some excellent articles, and the owner has spawned a second blog: mnmlist, which is all about living better with less.
So, if you're feel zennish, of feeling like you need to get your life simplified, head on over and have a look.
