Sounds like good exercise to do many times over, right? But it does little but aggravate you when you are doing this with your writing projects. I have been working on a novel on and off for a while, and what always happens is I will write a page, decide I want to do it differently, then either erase what I wrote and try to think of how I want to type it from there or I leave it and decide to come back to it later. Now I think you can guess where this gets me. Do you have the same problem? How do you deal with it?
