Since 2008, the Pope Center for Higher Education Policy has published articles about lessons learned in college. The series, “If I Knew Then What I Know Now,” is written mostly by students, who offer advice based on their experiences. That advice has ranged from encouraging other students to speak up in class to how to choose a major to practical recommendations such as avoiding credit-card debt. The latest in the series is different, however. In “Transition and Tragedy,” Zachary Williams explains how he tried, without complete success, to cope with the sudden death of his mother during his freshman year.
