Several years ago, the admissions director of an Ivy League university was asked for one or two high school activities that would give an applicant an advantage in being accepted to his institution, if they [sic] were on the waiting list. Without hesitating, he put cross-country at the top of the list. Cross-country runners, he said, have a special type of discipline and are willing to work very hard physically and mentally without receiving recognition. This combination of characteristics produced successful graduates who could handle the pressure-packed university culture.
