What #AdventOfCode feels like for me, living on GMT:
It's dark. It's cold. It's warm under my duvet. My alarm goes off. On the one hand, I could carry on sleeping. It's only a game.
On the other hand, I could get up, put the kettle on, and visit a world of islands in the sky and incompetent but hospitable elves, superimposed on a screen of code. Focusing my eyes and my brain on the day's instructions and wondering what twist Part 2 will deliver.
I can return to sit half-under my duvet, sip my tea in the semi-dark, before the rest of the world gets moving, and turn the elf-world stories into functions that give me a sense of warm satisfaction (ok, or blinding frustration) for the rest of the day.
That's how it feels for me.
@ludictech nailed it.
