there's times where i'm working on an art piece, and i'm so painfully aware of my own limitations. whether they be material (what supplies i have) or experience (how many hours i've spent honing in on something), but the bottom line is that sometimes i just become so aware that i don't know what i'm doing as adequately as i'd like to.
the knee jerk insecurity is that in a few years from now, i'll look down my nose at the piece with disdain. but truthfully, i tend to be kinder to my past self now than i was when i was younger since i realize the harm it can do. nevertheless, the insecurity remains.

to grow and learn is to brush against your own limitations. part of that is grieving not already being done growing and learning. it's rough!
it's tempting then to just not work on the piece/project, but obviously that means less introspection and improvement. it's just avoidance.

it's really walking a fine line? if you have too much ego, then you won't try challenging things so the illusion that there's nothing more for you to learn won't be broken.
meanwhile if you have too little ego, you'll lose the drive to take on challenging projects because you'll have such little faith in your discretion.
