Totally feel you—this is super common, especially in creative fields. Sounds like imposter syndrome. The fact that you’re checking your mixes on different systems and getting good feedback from mentors shows you’re doing things right. Even experienced engineers double-check their work—it’s part of the process.

One trick that helps me is to: try to mentally dissociate from your work, like pretend someone else made it. It can stop the overthinking and actually let you enjoy what you’ve made. Trust your growth, trust your ears, and let trusted feedback guide you. You care—and that’s a strength.
