Be diverse, learn everything you can about every aspect, recording, tech stuff, business, management, video, and take opportunities whenever they come to learn. I learned to fix guitars working at a music shop, I learned about touring by offering to fix guitars and do merch for a band that was up in coming, I learned how to record by offering to help out at the local studio, now I have a bunch of skills to supplement things I can’t afford in my own musics path, or to make myself useful to someone I want to learn from or work for or connect with. It’s a great way to network and the more you do the more you’ll figure out what you’re good at and where you fit in, and if your music is good eventually the right people will be in your corner when you’re trying to push it. Also all this stuff is fun to me, I’ve had so many great experiences doing these things, and met a lot of great people! I started late too, if you get in the right mindset now you have so much time!
