Recently, I've been thinking about writing fiction, and I admit, I tend to be less than super coming up with narratives about imaginary people and places. (Which is not to say that I haven't in the past, I just haven't pursued it with any determination recently.)
I mean, sure, I can take the advice of every creative writing teacher I've ever had and write about what I know, however, at some point when writing something untrue you have to eventually come up with something fake. It has to be something fabricated enough to count as fiction without feeling artificial. The characters have to move and act and think and most of all talk in realistic ways without being real.
Unfortunately (or not, depending on how you look at it) I tend to enjoy synthesizing aspects of ideas, and I am less than stellar understanding the motivations and desires of real people, let alone imitations that I've created. I'm getting better with time, and since the only way to continue improving is by doing it over and over again until I come up with something that isn't utter drivel, I had better get cracking and write something, even if the characters are wooden mouthpieces for my own philosophies.
It's better to have written poorly and sucked, than to have never written at all.
