That is interesting. We all have our different ways of writing though, and we have to find the way that works for us. So long as I know where I want my characters to end up I can usually finish something, but if they’re wandering aimlessly they’ll continue to do so until I write myself into a plot hole.
You don’t necessarily have to plot it all out. Having plotted some of my current stuff a lot more than ususual it has taken some of the fun out of writing a first draft, which is my favourite part. However, it’s also helped me to write the ideas down faster.
I think it’s about finding the right method for you. The more you write, the closer you’ll get to finding it!
Are you doing NaNoWriMo this year?
