The best preparation for being a parent wasn't NCT classes or books; it was managing a team of software engineers. My 4 and 2 year olds are far better at playing with others than those maladjusted coders.
@fesshole conversely, having kids was by far the best training to become a scrum master.
All the buzzwords and "ceremonies" and "artifacts" were pretentious guff. The team just needed a mum to support and encourage them, help them when they got stuck, and occasionally bring them snacks.
