I promise I’m not self-promoting. This is a genuine “I don’t know what I’m doing” and “I don’t know if I can do this” post

For a year now, I've had characters in mind that I wanted to write a story about. I got so into making the characters that I didn't consider worldbuilding or plot very much until I started writing a scene with a couple of them. And that's generally how I write: I don't think about what I want to write until I start writing it.

But then I realized if I was actually going to be serious about writing anything for these characters, I needed to have a plot. But I just couldn't come up with one. So I ended up asking AI to help me come up with a sort of plot. I had a few vague ideas about what I wanted to happen, but nothing clear or concrete.

AI gave me a plot and I decided it fit with what I wanted. But I can never get anywhere with it. I feel like I'm not cut out for writing stories--I don't have the focus or creative ability to do it. And I can never pin down exactly what I want to happen. It's a bit discouraging and like "why did I ever think I could do this?"

I'm sure everyone has experienced the feeling of not knowing what you're doing and/or not knowing where the heck to start, but it does make me wonder sometimes if I can truly write anything worthwhile
