So we know at the early stage of a person's life before they begin school, they have the potential to become any professional. So they can become a physician, they can become a nurse, they can become a police officer, a banker, a quantitative analyst. So basically at the early stages of our lives, we are totipotent. However, when we begin school and eventually when we get to college, in college, we have to choose our major. And once we choose our major, we basically determine the pathway that we're going to follow. And that pathway will eventually lead us to a certain type of career.
