Well...If I'm at work, then often something will occur to me, and I'll write it up, all the time trying to be as interesting as possible. If I'm not at work, then all bets are off. What I do do is tend to write something as a vague stream of consciousness thing, and only tidy it up a little. I'm guessing that this means I have some idea of what I want to say. Hmmm...you've given me something to think about.
