I have a short list of blog ideas that I maintain, to help me keep posting on a regular basis. (For the moment, we'll ignore the fact that I haven't exactly been posting "regularly"). One of those blog ideas is, how I come up with story ideas. I've held off on posting anything about this, as I wasn't really sure what to write.
You see, the funny thing is, I don't really know how I come up with story ideas. I don't really try to come up with original plot ideas, and it wouldn't take much knowledge of the genre to recognize this. If you look at any of the stories I've written, they are pretty standard fantasy themes: quest for the magical widget; David vs. Goliath; etc. But with that said, I do try to come up with my own unique angle on the classic plots. I'll let the reader decide if I have succeeded.
Of course there are many possible plot ideas to choose from - how do I select mine? Honestly, I just pick whatever interests me at the moment. The way I have it figured, this writing thing is a fun and interesting hobby. I do it for recreation, not to make a living. And since I'm doing it for fun, I might as well write about the stuff that catches my eye, and keeps my interest. So when you read any of my fiction, you know that I wrote it because, at the time anyway, it was an idea or plot or theme I was interested in exploring.
