"In narrative non-fiction, I know the entire story, and when I find a lull, I just look around in my memory for something that can keep the story interesting until the next thing happens. I know how it's going to end, so I have a certain amount of security while I'm writing, because I know where I'm going.
In fiction, I have no idea what's going to happen until it's actually happening. I mean, I have a basic outline, and I know that I have to get the guy from point A to point B, but everything that happens along the way is a mystery to me until I write it. This is really scary at first, but eventually it becomes pretty cool."
Wil Wheaton, of whom it can no longer really be said "who is probably best known as Star Trek's Wesley Crusher", has long been making the transition from performer of other people's words (read: actor) to creator of his own words (read: writer). Wil has only recently turned his attention to fiction. Like Douglas Adams in yesterday's quote, Wil is acknowledging the mysterious - and "scary"! - element of creating words from nothing more than the absence of words.
Interestingly, Wheaton is skilled in acting, an artistry foreign and scary to many writers, yet admits to pre-performance jitters when reading his own work (read his piece on seeing David Sedaris). How deeply felt must be the need to write to face such fear producing AND sharing one's writings?
