Above are a lot of good advices imho. But the main question should be “am i usefull to someone/something to get being paid for”. The main focus starts not from within you, but is depending on how the world around you is looking towards you. “Does someone want to give me money for what i am doing ?”
Talent alone is not enough. There might be hundreds of people who can do the same thing as you can do, and probably lots can do it a lot better. Having a mentor within the scene where your intrest is in, is also a must imo. Opportunities are literaly all around you, but you should be the one that gets it.
So it’s a competition in every aspect. Even if you decide to create your own opportunity by creating a business, you will notice that that competition is even more harsch and on every corner there is someone waiting to take your opportunities away.
I see a lot of people who try to make a living from their music. Very very few succeed in doing this, and by far the most have a second or even a third job. (music teaching, performance assisting, working in a music shop, working for steinberg…)
Fwiw to me the most important thing is that your main revenue is sorted out first. This might not be what you want to do forever, but this will allow you to work and progress towards the goal you’ve set for yourself without having the need to wonder what you are going to eat on a daily basis.
Many many years ago i had the same dream. Getting a life based on making and selling my music. Best thing that happened to me is that my parents didn’t allow me to do so, and since then i’ve been quite a lot of things, most of them succesfull, and i still have a good job, a good income, and… after 25 years of sitting home in the evening before my gear, i now finally play for crowds, being flown all over the place, and having fun in my very little spare time. Because i waited untill there was an opportunity, and i took it when it presented itself. Believe me, having a hobby as a musician is a way more fun approach, then having to wonder every day over and over again to find people who want to pay you, just for that single thing you apparantly can do well.
One last personal opinion that can be helpfull imho: learn to love what you are doing, instead of trying to do what you think you love to do. Thoughts change a lot over time.
