I mean YMMV. When I put in an effort to refuse the urge to think or say negative things about my art and tried to come up with general ideas rather than a specific image I had in my mind that the real project would never be able to replicate, I found I became a lot more satisfied with my own work because I was no longer comparing the results to an impossible to achieve version of it that I had in my head nor was I constantly hyperfocusing on the flaws. I instead just targeted aspects I wanted to improve at the most.
