I did my first set on Sunday at a Write-In I attended (oh, yeah I'm official this year) and was able to crank out 800 plus words in 15 minutes.If your a competitive soul, by all means try and beat me (you probably will).
The reason I like the word sprints is it's another way to break the novel writing marathon into manageable blocks. You have to write 1,667 words. Sound impossible? Sit down and write for 5 minutes. Shake it out. Go again. You'll hit the word count sooner than you think.
Keep an eye out. In a few weeks, I'll start bemoaning how much I hate my life and words.
Until then, happy writing!
