Derek, I like how you announced it only after actually doing it. This is much different than saying you're going to do it, which sounds obvious, but there is a big difference.
But keeping my mouth shut about it helped me slog through it and get it done, instead of basking in advance glory. It's too easy to slack off, if you've already felt the warm fuzzy joy from people's compliments on starting something. I didn't want to feel any of that until it was done.
