Lesson Learned

I thought I'd post a chapter on an old story that had 34,000 hits on Chapter 1 in 7yrs. It was only 6 chapters and they all had lots Hits and plenty of Kudos.
It was only a short chapter to decide if it was worth doing a few more. This chapter got more hits and more kudos than I expected and so I take this as a lesson learned.
I realised for me it's best that I should not to expect too much and just to keep stories to solo's or just a few chapters around 2000 words each.
Or I follow the trend and post longer stories in book form and don't consider comments and feedback to develop the story. Seems other regular authors sell their stories on Amazon rather than post on BC or am I wrong?
