I don't mean this in a condescending way at all. Just sharing something I realized myself after doing this for some time.

Everyone who plays guitar/sings/whatever first picked it up because they liked the idea of being a musician. It's the nature of the beast. For some people, that never changes. They like the identity so they write music to support it, this idea that they have of themselves. The thing about it is there's pretty much no incentive to improve or critique your work. The goal isn't writing great songs, the goal is being a musician, so you already have what you want. This is super, super common. I lived in a city renowned for it's music scene, and with a lot of the bands floating around there, you could tell all music was for them was a ticket into cool-ville. It worked too. They were the hippest of the hip around town, but their music was weak.

Some, though, start to write music for its own sake. Maybe it helps them live their lives, or maybe it's just a compulsion. If this is how you are, you're never complacent. You're doing it for the process of creation, not for the identity that it grants you (although that can be a nice perk). The bands and artists that everyone talks about on this subreddit, that's how it is for them. At least 99% of them. It's what makes their music great.

If I have any feedback I'd say try not to pigeonhole yourself by getting wrapped up in deciding that you are a singer-songwriter and immediately jumping to recording songs to support that image. Write music to write music, a lot of it, and whatever unique musical/personal identity that eventually emerges out of that process will be wild and real in ways that you couldn't imagine.

Anyway, if you're having fun with it, that is ultimately what matters. Just keep at it!
