I want to write science fiction. The operative word here is fiction, in that I need to come up with proper stories. I found a book "20 Master Plots", and I've read the sticky thread on the difference between plot and storyline. So what I really mean is that I need to come up with interesting story lines. How do I learn? A more basic task of "writing" is easily practiced, but only after I already have something to say. The fiction part is a whole new ballgame. There must be some way of practicing story-line creation before I'm fully capable of spinning complete and compelling yarns, right? Any suggestions or discussion, please?
