“A common and depressing assumption on the part of many college students is that they must stay on the academic rails until they are professionally established—go directly to grad school from college and directly from grad school to a job, as if there were some big rush and even a few years lost would put them catastrophically behind everyone else. Nonsense. Suppose you intend to retire at sixty-five. If you don’t start your career until you’re thirty, that still gives you thirty-five years to make it professionally. If you can’t make it in thirty-five years, you weren’t going to make it in forty or forty-five.”
