Every day do something for no other reason than its difficulty, so that when the hour of dire need draws nigh, it may find you not unnerved and untrained to stand the test. Asceticism in this sort of thing is like the insurance which you pay on your house and goods. The premium does you no good at the time, and possibly may never bring you a return; but if fire does come, it will be your salvation from ruin.

  • William James
