There is nothing better than 5:00 PM on Friday. A full weekend of being unplugged works wonders for me.
Of course, being a geek and all, I also use it as a time to work out some of the more complex problems without the pressure of actually working. There is just something about geek and workaholic that go hand-in-hand. Even away from the keyboard, I think about code I'll work on when I get there. Oh well.
I am off to clean the paintball gun. After all, nothing takes your mind off of work better than getting peppered with hot-pink paint. ;-)
