The problem I have with most time management techniques is that I'm a writer. Sometimes sitting down and trying to write for an hour is like trying to bleed a stone, some days it just isn't going to happen.

I've noticed I can easily get 3,000 words done in a few days without a problem, but the extra 2,000 words before I finish a chapter tends to screw me up. Suddenly I'm doing two jobs at once, I have to finish one story line but tie it to the next. I also hate the advice of 'you should write n words a day no matter what', because it's inherently useless advice. I don't write unless I'm writing something I know is half-way decent, I don't believe I should write simply for writings sake.

I don't think any programmer here would add an extra 500 lines of random code 'just cause'.
