I have so many ideas, and most are them are stupid. My strategy is working on whatever I think of until I don't like it anymore and posting whatever I like.
It depends on my investment in the story. I'm writing three stories. Two of them (I won't name names) I really wouldn't mind, assuming they were popular enough for that to even be a demand, of course. But the third one feels like my story. The story has been moving through evolving iterations...
Sometimes I look back on my midnight rantings and I'm like: that character wouldn't do that. Or: what does that even mean? It makes me wonder who wrote this? I did. I wrote it.
My characters are so cool sometimes. It makes me wish I could be them. Then I remember the agony they have coming in later chapters and no longer want to be them.
One time I read an old fantasy story I wrote in high school. It was mostly cringe, but there was this sex scene that surprised me with how well written it was. High school me clearly had priorities...
The ick is like a sudden blegh from someone you wouldn't expect it from. Like if you go on a date with a nice/normal seeming person and suddenly they're talking about how they never bathe and you're like yeuck.
