It is not the lack of ideas either. There are too many thoughts running around my head on a regular basis. The problem comes when it is time to extract and organize these ideas so that they make sense. Whenever I can't do this, it is frustrating.
I can go through multiple drafts, mainly with only a couple words scrawled on paper before they end up in the garbage. It is worse if I am working on a computer. I just type and delete, type and delete, and nothing gets done. It always happens with the writing I care about most.
Maybe it is time for a break.
