A quote
Encourage your friend to despise stout-heartedly those who upbraid him because he has sought the shade of retirement and has abdicated his career of honours, and, though he might have attained more, has preferred tranquillity to them all. Let him prove daily to these detractors how wisely he has looked out for his own interests. Those whom men envy will continue to march past him; some will be pushed out of the ranks, and others will fall. Prosperity is a turbulent thing; it torments itself. It stirs the brain in more ways than one, goading men on to various aims,—some to power, and others to high living. Some it puffs up; others it slackens and wholly enervates.
