I just can't be creative typing into a box on the screen, as I am now, after all. It's too busy, too noisy, too bright, too oppressive. When are they going to make silent desktop computers? The one I have has a solid state disc drive but still runs a cooling fan. (Notes: "Still Runs a Cooling Fan" possible bodice ripper?) I had to seek out my writing book and call up the old fountain pen out of retirement. So how did I get on? I spent a while getting the ink to flow (hint: put the nib for a second under a warm water tap). Then I wrote out something about why I'm not writing anything.
That turns out to be because I have no end in view. E. L. Doctorow (?) said that writing a novel is like driving unlit roads at night: you can only see as far ahead as your headlights reach but you can get to your destination that way, so not to worry. He might not have said not to worry. But that presupposes you know where you're going. Otherwise you're just driving around at night for no purpose. There might be novels that do that, perhaps Italo Calvino style, but more usually you need to know your ending. You don't need to know exactly how you're going to get there but when you start out, it helps to have an end in view, and I think in fact it's essential, at least for me.
So I wrote something like that in my writing book (A4 hard cover, spiral bound), admiring the flow of ink from the gold plated nib. And nothing else.
