"Wealthy men who use their wealth aright are a great power for good in the community, and help to upbuild that material national prosperity which must underlie national greatness; but if this were the only kind of success, the nation would be indeed poorly off. Successful statesmen, soldiers, sailors, explorers, historians, poets, and scientific men are also essential to national greatness, and, in fact, very much more essential than any mere successful business man can possibly be. The average man, into whom the average boy develops, is, of course, not going to be a marvel in any line, but, if he only chooses to try, he can be very good in any line, and the chances of his doing good work are immensely increased if he has trained his mind. Of course, if, as a result of his high-school, academy, or college experience, he gets to thinking that the only kind of learning is that to be found in books, he will do very little; but if he keeps his mental balance,—that is, if he shows character,—he will understand both what learning can do and what it cannot, and he will be all the better the more he can get."
