And if you are really, really stuck, and have been for a while, please don't use my call for a 2000 word day as more potential fodder for beating yourself up. Sometimes, a 50 word goal is really what we should try for. 50 words, before feeding the dogs (well, maybe after that), checking email, looking at text, or the latest sales at _________ (fill in the blank).
Do not judge the words, just get them on paper. And then 50 more. In a few days, you have a page, and a page becomes a paper. One foot in front of the other; it takes time to recover from periods of fallow.
