After 20 years of performing I can say a few things and I’ll keep it simple.
First, I don’t make music for a living but I do make music to stay alive.
Second, really think about the lifestyle that comes with it.
You will be providing entertainment for a bunch of drunk and/or drugged out people as your job(assuming music performance is the choice).
You’ll most likely not make much money and be tired all the time.
People won’t pay you sometimes
You’ll hang out in hot smoke filled environments a mostly.
You probably won’t be able to afford fancy new gear or have a music studio or own a house.
It’s possible that it won’t be the case but this is the most likely result.
Third,
If it grabs you, tears at your heart, and moves you like nothing else, then nothing I said above matters.
When those things start to matter, take a side route to make life easier but always keep the main path in sight. Your dreams morph and change as you get older and one of those side routes might help you to adapt to your ever changing dreams down the road.
Never stop growing and learning everything you can about everything that has a connection to your deepest heart path.
