You practice your favourite instrument and post it on the tube. Worth it.
You get to know people with similar style and taste so you jam together. Worth it.
You guys stream the sessions on Twitch and got fans. Release EPs on bandcamp. But it starts to take too much personal time away from you. Worth it?
But the fans want it! You'll have to decide. Sometimes you work for months on an album. People cheer on the live stream, but not a lot of income from selling the art. Worth it?
Pick your RUNLEVEL. :)
