NaNo: will I make it?

I managed to struggle up to 25,000 words yesterday, and I left work early today in the hope that I'd get plenty more done. Needing 25,000 more words in just 7 days, this is a necessity. So far today, I've written nothing. So it looks like it's going to be 25,000 words in 6 days now, with 4 of them at work. I'll never do it at this rate. Never.
