There's just always something that can be improved in my writing, and that bothers me. For example, the story that I'm writing now. I wrote the first chapter and was initially pleased with it. Upon rereading, I was still alright with it, but now I see where I should have fleshed that out and where that piece of dialogue is awkward and blah blah blah...
So I fixed it.
And then I reread it.
And that needed to be reworked and that wording was awkward and ew why did I change that it sounded WAY better the first way and so and and so forth.
It's a neverending freaking cycle! Haha.
