This is definitely in the category of advice (much like GTD) of "if you don't think you need this advice, you probably don't need it."

I feel like there's an alternate wording for this advice that is less "cut corners" and more "determine how many corners you don't want cut".

Maybe involving a target condition? You want to make the best thing possible. Keep on aiming for the best, but establish a baseline that you would find acceptable. Maybe you won't make something perfect, but you'll now have a target that you _can_ get to.

This thought process reframes the discussion of "good enough" away from "did I spend enough time on this? Surely I can spend another week and make it 10% better" to "Does this meet the requirements". There is no longer a debate to be had, just a yes or no question to answer.

So when people ship things that just aren't good enough you don't have a discussion around spending more time on things or being more careful, you have a discussion around what your baseline requirements are (which is _actually_ what you care about).
