You revise endlessly and can't trust any choice

This endless revising can feel like devotion to quality, but let us look at what it is really doing. Endless revision is often fear of finishing in disguise — as long as you keep revising, the work is not done and so cannot be judged or found wanting, and the perpetual reconsidering spares you the anxiety of committing to choices that might be wrong, so look honestly at whether it is truly improving the work or keeping you safe from completion. Past a point, revision stops improving and starts flattening — endless reconsidering can sand away the life and particular roughness that gave the work character, replacing vivid imperfection with dead perfection, so learn to sense when you have reached that point and stop, for the sake of the living work. And set a limit and let the choices stand — decide in advance a number of passes or a deadline at which the work is done, then honor your decisions rather than reopening them, for part of finishing is learning to trust a choice and let it stand. What keeps you reopening choices you've made?
