So we all have our own writing styles. Some people sit down and the words just start pouring out of them, happy little spigots of inspiration that were just waiting to be turned on the moment fingers hit the keyboard, while other people painstakingly plot out every step, every breath, every turn of the head that their characters make, which will lead them from page one to "the end".
I've tried almost every conceivable way to write and even though I've found that my technique falls somewhere in the middle of completely pantsing it, to having it all plotted out, I have found that one technique works for me every time.
Some people say it's impossible for them to picture what's going to happen to their characters in their head, but for me it's second nature. Maybe it's because I'm such a visual person anyway, or maybe it's because I'm somewhat obsessed with movies, but whatever the reason, it's very, very helpful for me to imagine my scenes before I write them.
I don't know everything that's going to be said, or every movement that will be made, but sitting back and watching my scenes unfold in my imagination makes it so much less intimidating to actually sit down and write.
Usually, after playing a scene out in my mind, I jot down the major events that I want to have unfold in my writing. This sort of an outline relaxes me because I'm not stressing out about what needs to happen and I can focus instead on how things happen.
What works for you?
