[T]hey differentiated being a varsity college athlete, preferably one that was also a national or Olympic champion, versus playing intramurals; having traveled the globe with a world-renowned orchestra as opposed to playing with a school chamber group; and having reached the summit of Everest or Kilimanjaro versus recreational hiking. The former activities were evidence of "true accomplishment" and dedication, whereas the latter were described as things that "anyone could do."
This seems perfectly reasonable to me. Almost all of the "top achievers" I know also demonstrate exceptional talent in a completely different field.
