My songs are bad but I think they’re good- how to be more realistic?

I want to develop as a writer, but sometimes I feel like I like songs only because I wrote them and not for what they actually are.

For example, the song I’m linking has been stuck in my head for days, but when I listen back to the recording I can tell it’s just not good.

How can I develop as a writer and realign my expectations with my abilities?
