I really struggled with the saying "finished is better than perfect" as I don't like doing less than a best effort. But I came to understand that for me, it means not agnoizing in the desision making area - is this the "prefect" border? is this the "perfect" block layout? - the things that can sometimes totally stall my progress. So now instead of wanting to explore every possible option, I find one that looks good and then stop looking.
I also know how to do $10 an hour work and $50 an hour work, so I decide ahead of time which one is the appropriate level. Neither are poor quality, it's just the level of perfection I strive for.
