To me, the most important and difficult thing about writing fiction is to find the plot. Good original plots are hard to come by. You never know when a lovely idea is going to flit suddenly into your mind, but by golly, when it does come along, you grab it with both hands and hold onto to it tight. The trick is to write it down at once, otherwise you'll forget it. A good plot is like a dream. If you don't write down your dream on paper the moment you wake up, the chances are you'll forget it, and it’ll be gone forever.
