How many people switch degrees? Only the people to whom the choice of degree - or even the choice to study in college - had not been a life-changing choice. Not all life-changing choices concern degrees. Nor do all people make such choices. But those who do, mostly make them at sixteen. (Mostly, not necessarily always. But definitely mostly.) I knew by sixteen where I was going in terms of studies and interests; including the painful choice not to go back to music. And as long as I have known Natalie, she has always known she wanted to be a doctor, and has made many efforts and sacrifices towards that goal. Those, to us, were life-changing decisions.
