Right now I'm at the planning stage of a piece of writing. It's just a pet project but I'm really enjoying it. I enjoy all stages of writing but planning might be my favorite, there's so much potential. However, I seem to second guess every decision I make. Nothing about the plot or characters or anything is perfect and every time I plan a detail there are two reactions in my brain: "this is amazing" and "this is stupid". When you write, do you know for sure when a decision you've made is the right one? Or are you constantly second guessing everything you write?
