Having less stuff: http://joshuaspodek.com/less_please. By this point I cringe when someone gives me a material gift, knowing I'll want to get rid of it soon. Most friends have learned I prefer a bottle of wine or scotch as a gift to anything to stick on a shelf.

My exercise regiment has me in as good physical shape as I've ever been (including when I ran marathons and competed at Nationals level in Ultimate Frisbee). Here's how I work out every day with no gym membership, cost, or equipment, enjoying it: http://joshuaspodek.com/how-begin-workout-routine and http://joshuaspodek.com/knew-minute-day-workout

Personal development for free, the equal of any multi-thousand-dollar seminar: http://joshuaspodek.com/vipassana-meditation

Lots of other examples if you dig through my blog.
