I've fit this pattern for most of the things I build, though I'd replace "days" with "weeks" above. The things I have finished are nearly all things I have put a price tag on. They may have been done before I shipped them, but most weren't. But once there's the threat of real users sending you money and expecting things to work, that's incentive enough to actually wrap up loose ends and polish what's there. Notice that what actually happened was a slight redefinition of "finished" to include all the features that currently work, with non-working features hidden and no pointy bits sticking out the sides. As distinct from "all the things I wanted to include are now working to my satisfaction." Eventually you can work toward including all those other things, but step one is to polish what's there. Then it's just a matter of polishing each additional feature after they're built and before they're exposed to users.
