I'm not sure if anyone else has this problem but it is quite a hindrance to my own writing. My mind has a habit of drifting off when I write. Sometimes this is good, if it is relevant to the story, but quite often it is unrelated ideas for a different story and I cannot get back on track for some time. I do jot down these ideas for future reference but it is quite a pain? Does anyone else have this problem? How would you recommend tackling it?
