Winston ChurchillI now began for the first time to envy those young cubs at the university who had fine scholars to tell them what was what; professors who had devoted their lives to mastering and focusing ideas in every branch of learning; who were eager to distribute the treasures they had gathered before they were overtaken by the night. But now I pity undergraduates, when I see what frivolous lives many of them lead in the midst of precious fleeting opportunity. After all, a man's Life must be nailed to a cross either of Thought or Action. Without work there is no play.
Winston Churchill
