What’s the hardest part of finishing long-form writing for you?

One of the reasons I built Quill is that I kept hearing the same thing from writers:

“I know what I want to write — I just can’t stay organized or keep momentum long enough to finish.”

I’m curious:

• Where do you personally get stuck when working on long-form writing?

• Planning? Structure? Consistency? Motivation?

I’m actively shaping Quill with early users, so I’d genuinely love to hear what’s been hardest for you — even if Quill isn’t the answer yet.
