Advent of Code Results Day

I ended up in 2nd place overall in my company's private leaderboard for Advent of Code. 3rd place is still in flux (people have until the new year to catch up on puzzles they missed), but my ranking should be locked in now.

This year's puzzles felt a lot more demanding than last year's, but in comparing the times, it looks like I spent about the same total time working on them.

Now to resume my classic old person schedule of "going to bed between 9 and 10 PM" and my classic overachiever schedule of "waking up between 5 and 6 AM"!
