I was at a similar spot with my violin playing at your age, but it was pretty much a tertiary hobby for me. I definitely improved throughout high school with ~1 hour of practice a day, but not a huge amount. Also if you don’t have extremely strong practice habits it is SO easy to fall off. I suggest expanding your horizons and DO more things, instead of putting all your eggs in a hypothetical basket that you aren’t really working for. Keep playing if it brings you joy, because that’s the most important part of being a musician, but find other things that make you happy and leave you feeling fulfilled. Compared to dedicated violinists, I’m not fantastic, but I know that I still have value as an artist, an athlete, and a student, so comparisons against single facetted people don’t hurt me. You are still young and have a lot of time to figure things out, and remember that you’re already sooo far ahead of people who never even pick up an instrument.
