This post gives us some a good idea of what kind of writer we happen to be: Plotter, Pantser or Plotser? Or maybe a little of each? I tend to be very methodical and organized, but I don’t like to translate that to my writing. I like to feel free to be able to create whatever characters and worlds I choose.
However, it does help to have an idea of where you want to go. I agree with having a very basic plan when starting. This post will give you that quick plan–if you’re not sure where to start.
No matter which kind of writer you are, just start! That’s the key to getting your book completed.
