When I was a graduate student in the mid-1950s, I could read all the journals and conference proceedings; I could stay current in all the discipline. Today my intellectual life has seen me regretfully kissing subdiscipline interests good-bye one by one, as my portfolio has continuously overflowed beyond mastery. Too many interests, too many exciting opportunities for learning, research, and thought. What a marvelous predicament! Not only is the end not in sight, the pace is not slackening. We have many future joys.
