Something is better than nothing.
Is it really important that it is perfect? Who really cares?
What do you win by doing this imperfectly (time - to achieve other / more meaningful things, or to rest, or to spend time with people you care about, or for your hobbies)
What do you lose by doing this imperfectly? Not much usually.
Who will notice? Probably nobody.
In the grand scheme of things, why bother anyway?
What are you trying to achieve? This task perfectly, or this task is just a something you need to do to get paid so you can have a meaningful life?
If people do care for a specific aspect/corner, they'll tell you anyway.
They probably prefer seeing something earlier so they can give feedback, so you can achieve an even better result, counter-intuitively.
Besides all this, I think I achieve this by not caring so much and not tying myself personally to much to the task. And by thinking about the outcome. Perfect often leads to worse outcome, and is relative to only you anyway because other people care about other stuff than you.
Of course, it is still important to achieve the task correctly, but as perfectionist we usually need to take a step back.
