“Happiness can not come to any man capable of enjoying true happiness unless it comes as the sequel to duty well and honestly done.”
1900s, Address at the Prize Day Exercises at Groton School (1904)
Context: If there ever was a pursuit which stultified itself by its very conditions, it is the pursuit of pleasure as the all-sufficing end of life. Happiness can not come to any man capable of enjoying true happiness unless it comes as the sequel to duty well and honestly done. To do that duty you need to have more than one trait.

Context: To adore, to understand, to receive, to feel, to give, to act: there is my law my duty, my happiness, my heaven. Let come what come will — even death. Only be at peace with self, live in the presence of God, in communion with Him, and leave the guidance of existence to those universal powers against whom thou canst do nothing! If death gives me time, so much the better. If its summons is near, so much the better still; if a half-death overtake me, still so much the better, for so the path of success is closed to me only that I may find opening before me the path of heroism, of moral greatness and resignation. Every life has its potentiality of greatness, and as it is impossible to be outside God, the best is consciously to dwell in Him.
