Perfectionism is different from the concept of perfection. Perfectionism is the idea of holding back because you don’t want to proceed and using imperceptible flaws as an excuse to hold back. This is different from saying something is "not good enough." The words ‘good enough’ simply means it meets the required standards and it doesn’t have to be better because if it was better, it wouldn’t qualify as "good enough." I think the way to develop good taste involves actively sharing creations with the world, observing what connects and what doesn't and it's through this process that one refines their understanding of quality.
