If you hang around long enough you'll end up with code you once wrote that was maybe a quick fix, maybe you thought it was brilliant, but now appears to you as a steaming pile of crap. Sometimes it may however still be the best solution but your future self was unable to figure out why because your former self was too lazy to properly document the code.
