Go camping for a weekend, and deliberately step away from projects, church, and the like. Maybe take one or more of your kids with you, but don't schedule the crap out of the weekend, just find a good place where you can toss your line into the lake and read a book or listen to music while you wait for the fish to bite.

We all need a mental and physical break now and then, and that doesn't just refer to paid employment, but all of our responsibilities.
