Did my first weekend hackathon and swung between "this is the best thing I've ever done" and "I want to quit tech" within twelve hours

Team of four, built a scrappy prototype in about 30 hours, barely slept. Hour 20 I was convinced we were making something genuinely cool. Hour 26 I was questioning every decision I've made in my career. We didn't place, but I learned more about actually shipping under pressure in one weekend than in months of solo tutorial-following. Would still do it again, just wasn't ready for the emotional whiplash.
