You know what must be done and it won't REALLY take that long. Close the nice clean bedroom's door, grab the broom and/or the vacuum and give the rest of the house a good round of detritus removal.
Listen to some music or a book on headphones (with an iPod or what have you) while you do this and it will go even easier.
When you're done, look around. The place looks pretty decent, huh? Enjoy the weekend!
