I didn't make my quota yesterday, because I was called in to teach, then went food shopping with my mother at night. I don't know that NaNoWriMo is the best way to write a book. It certainly isn't the only way.
If it works for you--good. I see that even if I bashed out a "novel" or rough draft in one month, I still would need to spend the next 10-11 months rewriting, editing, and polishing it.
