One cautionary note: Beware pushing/powering through incipient burnout, rather than addressing it. "Emotional debt" can be hard to pay off. I've had valuable projects that I was very reluctant to touch again, even years later.
This is a good call. And letting frustration roll off your back. If I let frustration get to me, I would have quit. If I couldn't accept 'little progress', (when the alternative was no progress), then I wouldn't have made little progress daily, and gotten to the point of almost done. This is something I've heard (perhaps mostly anecdotal), where people shift between neglect and perfectionism. Allowing moderate progress (where you're not meeting your standards for progress 100%, but you are moving forward), is actually difficult to accept, but it's usually a pretty good coarse. It's hard to be the turtle.
