Here's a good idea:
The Rule of 200 works like this: my document word count must increase by 200 before I am done for the day, no exceptions. 200 words is a modest goal. It isn't even an entire page of double-spaced 12pt font. It's a grocery list, an email, a series of text messages; it's a lot shorter than most of my ProfHacker posts (this one included). Sometimes it takes me 15 minutes to write 200 words. Sometimes it takes all day long. But no matter what, before my head hits the pillow for the night, the word count is +200.
I write 200 words a day, every single day, until I have an entire draft. "Every single day" includes weekends, long days on campus, holidays, even my own birthday.
- so writes Erin E. Templeton, blogging for ProfHacker at the Chronicle for Higher Education. The idea reminds me of my favorite quotation from Anthony Trollope: "A small daily task, if it be really daily, will beat the labours of a spasmodic Hercules." Two hundred words feels like a really achievable daily goal.
