Winning National Novel Writing Month. I know that NaNoWriMo is in November, but I reserve the right to change February into another November in my personal timeline. I just have 618 words left. I've never written anything longer than about twenty pages before, and no fiction, so this was really a new and exciting experience for me. To my surprise, the book is actually pretty fun to read; I was expecting it to suck. I didn't know that any of this was even possible for me. This really has been an amazing month, and I look forward to doing it again when the official November comes around.
(On a more nerdy note, none of the existing word processors really felt right to me, so I'm using a text format of my own devising, a python script to convert it into TeX with the memoir document class, and emacs. And org-mode to handle the story notes. It's remarkably pleasant, and it was a fun way of procrastinating. Much like writing this post.)
