Went skydiving (technically still during my exams but whatever), got a full time job, started exercising regularly and eating healthier, got a credit card, drove down to Canberra to give a lecture at ANU for the olympiad kids at their summer camp and broke down on the highway and got to see an awesome rural sunset in the process, tried clubbing (and hated it), got a pub trivia team together with friends for weekly games, started an online maths/computing course on Coursera.org, and slept. A lot.
