Well, this is an exciting part of the story.
If I were younger and less experienced, I know what I'd do: I'd stay up even later, writing more and more and more; and then I'd have to go back tomorrow and redo about half of it for this or that reason. Experience has taught me to stop writing when I start feeling tired, lest I screw something up.
Patience and discipline.
I'm having fun writing this; and I know that when I have fun writing something, people will have fun reading it. That's how it worked for $RELEASE_CANDIDATE_ONE, anyway, and just about everything else I've pounded out over the years.
Anyway, now it's time for me to proofread what I've written, and then brush my teeth and go to bed. I'll write more tomorrow, God willing.
