So here's a thing that might help. Might also help to explain to some people 1 of the differences between western and eastern artists.
The thing you are dealing with is self esteem (literally had to look up that term lol) but in asia, self esteem wasn't a concept that existed until recently. I won't pretend I didn't hear about this study through an excellent podcast but basically, what was outlined in their study was that when westerners did bad on a test, they pretty much gave up because they figured they weren't good at it so why try. Easterners just became more driven and went 'hard on the paint' to get better. But, the opposite happened when they found they did well. Westerners chase the things they are good at to become better than people around them and make themselves special individuals. Whereas the easterners saw they were doing good and just began to be a bit lax in that particular area of study.
Anyway, I like to use that study to see that no matter what you find in your attempts, you can get yourself to work harder and do better. Whether you are doing better or worse, you just have to work through it. One of my favorite sayings, 'If you're going through hell, keep going'
But I think sycra covered it as well when they mentioned stuff about the balance between a more refined eye and what we are capable of at the moment. There's another bias which is the dunning kruger effect. Which tells us that the less capable we are, the less errors we see in our work. The inverse is also true. The more capable we and and that we become, the more crap you will see in your work. It's kind of odd to think about it this way but try and remember that the more clearly you can see that your stuff sucks, the better it is for you in the future, AS LONG AS YOU ACTUALLY WORK TO CORRECT YOUR ERRORS HONESTLY.
That being said another bias is also real, the Imposter's Syndrome, where we can't internalize our own accomplishments. We become pretty blind to the progress we have made. One thing I really like to do to help myself out is not only look at my old stuff, but to look at the stuff I really enjoyed when I was much younger, the stuff that really inspired me when I was at that age. Then compare it to the stuff I can do now. I am pretty surprised at how close or how far I have passed that work that was made back then. I personally struggle with finding my own work to be of any worth but I remember how those pieces made me feel when I was little. See what I can do now, and wonder if I can actually do the same for others that others have done for me. Even though they weren't masters. Really motivates me :3
Anyway, sorry if I rambled a bit. But I hope any of what I have said helps.
