Stop now 或者 a few 更多 chapters?

Ok, so, anyone who reads my fanfiction, Lanky, Cranky, 食物 Jones, would know that there are A LOT of chapters. I originally wanted to only write 10, but I couldn't stop. I was thinking now I could try and stop at 20. The most I would write would be 25, but I think that's way too many. Opinions? Thanks.
