I'd say I'm in the same boat I always wonder if what I'm writing is good (or if I can "fix it' and "make it good" once I get to more of an editing process.) Which stunts my creativity.
Sometimes I wonder why I bother to write at all. Sometimes it feels more like a 'need' than a 'want.' (if that makes sense)
I guess, 'writing for myself has been about feeding my desire to learn and grow in a new skill. I'm a daydreamer, always have been, so I wanted to learn more about writing skills like novels and
fiction, non fiction how to turn my daydreams and ideas into concrete things.
