We've all either participated in (or at the very least heard of) NaNoWriMo. Last year was my first go at it and all I felt when it was over was, "I don't want this to be over!" Though I'd added 64,000 words to my manuscript, I still wasn't anywhere near finished.
After thinking about it, I really began to feel like a month just wasn't enough to really pull it off. Not for me, and probably not for most of us. It felt more like a three month project:
Month 1: Planning, Outlining, Researching, Synopsizing, etc.
Month 2: Fast and Furious Writing from the Heart.
Month 3: Somewhat Slower but No Less Furious Rewriting with the Head.
