Fall.

Ribera, Euclid (detail), 1635

Rather than literally burning the midnight oil, which he judged to be unhealthy, John Adams advised his son to make the most of college by developing an inquisitive outlook that would prompt him to get to know the most exceptional scholars and question them closely. "Ask them about their tutors, manner of teaching. Observe what books lie on their tables. Fall into questions of literature, science, or what you will."
