Sketching Out Your World
I found out early on that sketching out scenes helped to keep some order to the chaos of writing. Recently, I found a few old sketches for my book. They were a HUGE help, and it was fun to look back and see what had changed since drawing them.
Sketching out the Bottomless Well helped me quite a bit. It helped slow the scene down in my head and visualize the movie into the next chapter.
By the way, you don't have to be good at drawing... as you can clearly see... it's just a tool to help YOU keep your world in order.
