It’s not uncommon for me to be dissatisfied with things that I produce. When this happens, different things can occur:
I despise what just happened and think how much time I wasted, how much I probably suck and give up.
I see what I did wrong and think about improving them, but I procrastinate on it and eventually forget about it.
I see what I did wrong and think about improving them, but I procrastinate on it for so long that by the time I try again, I barely make an improvement.
I see what I did wrong and instantly try again.
All of these scenarios could be argued as valid reasoning, but my disciplined side of me is trying to make the latter habitual. (And I'm trying make that disciplined side of me a more prominent figure).
