well if you want my two cents here it is:
I echo what others say about how we are not satisfied with our work. That is good as long as it pushes you to improve but not if it stops growth.
FWIW I saw the most gain in my photography by two things: taking lots of shots and studying not only my successes but my failures have taught me even more- especially the 'near misses'. I studied them and then tried again. And again and again. Not that I rate myself that high but I have fun and am still advancing so what the heck.
Another piece of advice that I might give is to stop buying stuff and studying stuff and just go out and take photos. and more photos. Learn the equipment that you have.
When I take a photo I try to stop and think about what it was that attracted me to take the shot and how would I convey that to the viewer.
