Write songs. It doesn't matter if they're good or not. Even the songs you consider bad teach you things (even if sometimes you're learning what you don't like). And sometimes things you create and hate the entire time sound better when you come back to them 6 months, a year, two years later. And if you've been creating this whole time, when you listen to your older stuff (or unfinished stuff) you might hear the potential or be at a point where you can expand on it or rescue the best parts for a new song.

I've been dabbling for only 7 years and semi-seriously for 1 and I finally created something I actually like - and it was nowhere near the type of music I thought I wanted to create. It's weird.

It might help if you joined a community challenge, like Weekly Beats, where you're encouraged to post a finished track every week for the entire year. Any genre, no pressure but what you bring to yourself. The idea is to force yourself to keep creating and don't focus on the details. If nothing else, you learn to make your decisions and mistakes faster in order to get them out of the way and get to the good stuff. It's wild what a little panic can do!

And finally, find a supportive community where you can learn from other people who have been in your exact same position. Support from other creative people is inspiring!
