Leisure consists in all those virtuous activities by which a man grows morally, intellectually, and spiritually. It is that which makes a life worth living.
What is morally wrong can never be advantageous, even when it enables you to make some gain that you believe to be to your advantage. The mere act of believing that some wrongful course of action constitutes an advantage is pernicious.
It is not easy to distinguish between true and false affection, unless there occur one of those crises in which, as gold is tried by fire, so a faithful friendship may be tested by danger.
