10. Lose 10 pounds! 

Or, in my case, a few more than 10. Small spaces often have narrow passageways and very little wiggle room. I know for sure that I would have a tough time getting the job done in the Tiny Tack House's minute shower, and I'd probably scrape the walls of the kitchen as I walked through it. But, hey, I gotta ask myself—am I dedicated to this small space thing or not? No pain, no gain.
