Woke up apathetic. Spent an hour negotiating whether to go. Went anyway. Built an event manager with strangers in a hackathon loft. Slipped out at three for coffee and a waffle — the small reward when the room's been airless for four hours. By five we made the shortlist. Pitched. Came home to half-packed boxes, stood in the kitchen running a breath practice until the shoulders dropped. Some hackathons you enter because you couldn't find a reason not to go.
