I’m not young anymore either. I’m going to be 39 in August.
BUT…I started when I was 19. I wished I could have started sooner, but I didn’t have the income to buy gear and music until after high school.
I did play saxophone from 4th grade all the way into my first year of college, but stopped since EDM was calling me more than jazz or concert music.
I will say you younger DJs are at an advantage. Your life is merely school, your peers, and such. You can build a following here that will follow you into adulthood. Seen many locals grow big simply because they had the kickstart of playing house parties and school dances for their peers. It’s harder when you’re not in school and thus can’t easily promote to your peers…or your peers have gotten older and now aren’t going out clubbing anymore.
Use this time to perfect your technique, keep producing, and grow. Build a fanbase in your high school and carry them into college. Play people’s house parties and school dances if you can.
When you get a little older (17, 18, 19, 20)…network in the rave scene or look into teen clubs for possible gigs.
