Working 9 to 5

I'm volunteering this week at a non-profit org that would be really kick-ass to work for, and I'm volunteering basically 9 to 5 every day this week to get a feel for the place. Let me tell you, I'm already exhausted. I don't know how people do it--9 to 5, trying to make a living--but graduation is coming soon and I think I need a little more Dolly Parton in my life to easy the road.
