"During his senior year of college, Summers was considering graduate school in both theoretical physics and economics. For weeks, he anguished over whether to pursue his passion (physics) or the family business (in addition to his economist parents, Summers has two uncles -- Paul Samuelson and Kenneth Arrow -- who won Nobel prizes in the field). After he finally decided on the latter, he explained his thinking to Rollins: "What does a bad theoretical physicist do for a living? He walks into an office, sits at a desk, and stares at a plain white sheet of paper." "But," Summers added, "there's a lot of work in the world for a bad economist"."
