"Fleshing" out a story.

I am trying to get back to writing; reading a few of my old stories to see what I liked and thinking. The first story I published on this site, drew a comment that said something like, you have a nice little story here that needs fleshing out. Another said that my story rambled a lot.

So, I decided that before I forged ahead on finishing my last story, I would try to conduct a little "self seminar" to try to tune myself up. Who knows maybe I need a book called, "A Tune Up For Wanna Be Writers"? :)

Suggestions please?
