Your blog is fantastic and I'm impressed by your free guide. You are a busy bee, heroicmuse.
50,000 words in a month is about 1,666 words a day. I think that may be a good goal for people who have a hard time being disciplined about writing. I write most days a week, I'd say at least 5 days. I would also say I rarely get to 1,600 words, but I probably do 500-1,000 words, somewhere in there. So I probably won't join the competition, but I love the idea.
