Moq,
While still in his 30s, Rov Soloveitchik z’tz’l was a member of the Moetzes Gedolei HaTorah of Agudath Israel of America, Rosh Yeshiva of Yeshiva Rabbi Yitzchak Elchanan, and de facto Chief Rabbi of Boston. He probably would have had those kinds of accomplishments in his 20s except that he took time out to attend college in Poland and earn a doctorate in German philosophy in Berlin.
