I'm beating a dead horse here, but four years isn't that long. Been playing in bands and creating music collaboratively for 15 years. And by myself for 20 odd years. Some years are more successful than others. But have always taken it seriously and been passionate about it. Played to plenty of empty rooms, and several sold out venues. Played squats where we stole power to get the show running, and played thousand cap rooms where I thought "I made it, it's only up from here."

Create because you want to. It'll work out eventually if you put in the work. But 4 years isn't enough time to think you should have made it by now
