I am sometimes the opposite, and sometimes almost-perfectionist, returning again for better light or situations. That's OK to keep coming back for more and better. I pick nearby subjects though.

I like the holga suggestion. Some alt process or soft focus lenses might get you less paralyzed and more creative too. Frederick Evans did some nice pictorialism architecture and that would get you away from the detail oriented process. The alt process part would make the medium an integral part of your work, making you a craftsman as well as someone able to capture images on film.
