It used to be that, as a musician, only 10% of your career was up to you. “Getting discovered” was about all you could do. A few gatekeepers controlled ALL outlets. You had to impress one of these magic few people to be allowed to present your music to the world. (Even then, they assigned you a manager, stylist, producer, band, etc.)
As of the last few years, now 90% of your career is up to you. You have all the tools to make it happen.
