Sometimes, though, this procrastination does wonders. Like bonzai tree gardening, or a Zen gravel garden.
As someone who uses Gentoo, Xmonad, Zshell, and Emacs, there's more than enough config code to tweak than there are hours in the day. The happy result is that if I'm stumped, I always know I can pop open a buffer and hack something a bit.
Hell, the alternative to wasting your time in a fully hackable environment is wasting your time on the interwebs.
If you're going to procrastinate, you could do worse than by hacking .emacs. Like Runescape.
