Spoke Too Soon

So, I was doing great on the fourth, I really was, and then I finished the exposition, and I crashed.

I haven't written a single word today. Once the introduction was finished, I didn't know where the story went from there. I still don't know where it goes. Sure, I know what they're going to do and what's supposed to happen, but it's not as planned out, and I'm still iffy on a lot of details. That blank page keeps staring at me with the little curser blinking and I don't know what to say. Maybe something will come to me, or maybe I'll get excited about my novel again but all of the momentum I had came to jarring halt the second I finished off the fourth chapter yesterday night.
