The other day I read a Twitter post asking writers how they developed their ideas. I had to think about this for a while. How do I develop my ideas?
Many times I will wake up in the middle of the night, full of ideas for new stories. New plots, new characters, and conflicts will pop into my mind in the middle of the night. I will think of new things in the weirdest places, like my shower or shopping, that I must carry a notebook around with me to write everything down in. I have a notebook by my bed to write things in in the middle of the night. Sometimes those ideas will not make much sense in the mornings but it has worked many other times.
That is my "process". I don't have any magical rituals, I simply have times when ideas come to me.
