One of the age-old writing principles is to write less. Detail is fine, clutter is not. But we like to fill up space. We’re compelled to fill blank pages with content, even if it dilutes what we’re saying.
To combat this tendency increase the size of the text you write with and give yourself less space to fill.
Within TextMate, for example I write with size 14 text and have it so the text wraps after 78 characters. This means that even a small paragraph fills up plenty of space, satisfying my ego while deflating the word count.
