I don't understand 9-5 either, why start so late? I do 7:30 to 4, and get out in time to go surfing, sailing, or skiing depending on the season. Or maybe just hang out on the beach with my girlfriend. Or maybe BBQ with some friends. Or get a nice book at the library. Or hop online and play Starcraft. Or watch a good movie. Or maybe, spend some time working on my sideproject or programming in general.
Work to live. Don't live to work.
