weaving a dream

It has always been my dream to write...anything will do from stories to actual novels. I have never had the patience to sit down and finish one, though. I seem to have a problem with ending them. Closure, I suppose, is really among my issues(sigh...in paper and in real life experiences). There are times when stories seem to be nagging me. They seem to be playing in my mind out of a simple impetus from my student's experience to something that I see like the pen on the floor or something as random. I wonder if I have enough creative juices or energy to put these stories on paper. Or better still will the writing muse come and save me?
