I've been doing that lately with cleaning my barn, which is partly disorganized and partly too much junk, both mine and the previous owner's. I'd been telling myself to set aside a day or two to tear into it and get it all done, and it never happened. So lately I go out every day on my lunch break and work at it for 15 minutes.

It's not as efficient as doing it all at once, since it takes a minute to look around and pick something to do next. But I'm making progress, which I wasn't at all before.
