Sounds like me. What I've found helpful is to reduce the scope of the project. Focus on base hits rather than home runs.

Not quite the same as "MVP" if MVP implies permission to release something crappy and incomplete.

I shoot for something small, polished and excellent.

The finishing stretch is hard. One has to learn to enjoy this process; documenting, adding unit tests (if needed), jumping through hoops like CPAN or the app store.

I think finishing is a habit we can build.
