finishing things

I've been trying to do things more quickly. To just get things done, even if they're not great.
This involves knowing that I put, say, an hour into something, and what I came up with is reasonable for an hour's work.
Some things I just take forever on. I was trying to understand why. I have this image of certain important things that are very fragile and complicated. I picture a many armed Hindu God carrying many plates, each with a crucial element that needs to eventually be combined with something else. But this God is on rather shaky footing, and must hop continually in order to avoid dropping one of the plates. Anything that touches on this domain must be treated very carefully, because it won't be a top priority. It needs to make sure it doesn't break anything, and the very process of doing it may involve helping to combine together some of the plates.
I don't think there's anything to be done accept to realize when something can be done independently of this blue creature. Then it can just be finished in its usual partial messy way, but not cause so much damage.
