I scored the highest tertiary entrance rank in my school without studying a day in my life and had my pick of any university course or career. I went to university, and excelled at exams, but because I had undiagnosed ADHD and had never learned time management, I couldn't cope with assignments that couldn't be thrown together at the last minute in my lunch break. I was academically excluded.
So there was that. Basically, my life has continued to look like some variation of that experience since then :P
