Rabbit or Turtle

With just over three hours to NaNoWriMo, I am wondering whether to start as a rabbit, write fast and take a chance on burnout. Or write like a turtle, slow and steady. I don't write on Sunday, so I only have 26 days to actually get to those 50,000 or more words. That is just under 2000 words a day. I know I can write 2000 words a day no problem. However, can I do it for 26 days? I have tried for the past three years, and not finished. Last year I only got half-way. It is discouraging. I am going to try a lot harder this year. I need to do this for my sanity.
