As someone who has been in the professional music scene for over a decade trying to ‘break through’ and has seen many others trying the same, sometimes it’s about how good people are at their instrument/songwriting/art but more often it’s about luck and what connections and/or funding you have. I’ve seen people who are truly creative and work hard build impressive success from basically nothing. I also know plenty of people who are just as creative and hardworking spin their wheels and get nowhere. Frankly, i suspect this has always been the case. Ability alone has very very rarely been enough to attract great attention. In the stories of most big names you know there is something somewhere along the way where they either were lucky enough to be in the right place at the right time or just come from enough money to be able to give it their full attention for years, and even then they usually need some other kind of luck.
My point is not to discourage though, but rather to say that if you want to make art to become well known then in my opinion you’re doing it for the wrong reasons. Also, if you truly like a creator you should spread the word, tell your friends, tell strangers on the internet! It’s hard to convince people to give your art a try, but if someone else is doing some evangelizing it becomes much easier.
