It shouldn't be your followers/readers job to motivate you to write, do it because you wanted to write it in the first place. Don't tell them to either vote/comment or you're not gonna make another chapter. Ive seen this on so many books and those are the ones I just remove from my library without voting on. I know I'm the most judgmental prick of a reader but readers like me shouldn't be the reason you stop writing. Don't let your readers decide if you should make another chapter, its up to you.
