On this 149th anniversary of his birth, I offer a quote from a letter TR wrote to his son, Ted, when the boy was in college.
Blessed old fellow, you had a pretty hard time in college this fall. But it can't be helped, Ted. As one grows older, the bitter and the sweet keep coming together. The only thing to do is to grin and bear it; to flinch as little as possible under the punishment, and to keep pegging steadily away until the luck turns.
