If a non-polished (or is that just not-good-enough?) work result comes with negative consequences at a future point in time, of course polishing reduces the opportunity for some urgent fire-fighting activities, and reduces the possibility to become the hero to solve the problem. If it's just some work output for the purpose of practicing / studying, it wont come with such consequences. No-one is going to read it next year, and even if, it won't matter. Fail/pass quickly for practice, to get the experience to work carefully for when it matters.
