Earth Hour is tonight, at 8:30 pm wherever you happen to be. So turn off your lights, step away from the computer, do what you can to reduce your energy consumption. Have a late candle-lit dinner or a nap with your beloved (wink, wink, nudge, nudge knowwhatimean?).
Then, take that initiative and carry it forward to tomorrow. Hang your clothes to dry or walk to work. Cause your planet loves you, you should return the favor.
(Me? I'm going to have a relaxing bath tonight, BECAUSE THAT SUCKER IS TILED NOW. Woot!)
(The candlelight will help me ignore the drywall dust and mortar that's still all over the place.)
