Take Regular Breaks!
by Eoghan Fearon
When you write for long periods of time in one go, you wind up with tired eyes and a tired mind, and slowly you start to write twoddle, even if your mind is burning with what to put down next. A fresh mind can examine things in a new light and pick out flaws that you missed before.
At least every hour, preferably half hour, get up, walk around, make a cup of tea, go for a walk, watch TV, play a video game, cook, go for a run, go for a shower, sleep, just do anything that takes you out of the setting you write in and puts your mind on something else for a little while.
