how do you create good and worthwhile things if you do not try and make them better? how will you make them better without finding the elements that can be improved and improving them? maybe this is part of the engineering mindset, the ability to approach the world with "how can I make this better" and not be depressed and overwhelmed.

I used to get super frustrated and depressed when people edited my writing/prose. each comment was some way in which I sucked. then I compared, side by side, my early drafts with finished works. now I'm not frustrated or depressed when people find problems with my writing! or my code.
