physician, 'It is not by being anxious in an inordinate or unduly fussy fashion that men can hope to live long and well. The best way to live well is to work well. Good work is the daily test and safeguard of personal health.... The practical aim should be to live an orderly and natural life. We were not intended to pick our way through the world trembling at every step.... It is worse than vain, for it encourages and increases the evil it attempts to relieve.... I firmly believe one half of the confirmed invalids of the day could be cured of their maladies if they were compelled to live busy and active lives and had no time to fret over their miseries.... One of the most seductive and mischievous of errors in self-management is the practice of giving way to inertia, weakness and depression.... Those who desire to live should settle this well in their minds, that nerve power is the force of life and that the will has a wondrously strong and direct influence over the body through the brain and the nervous system.'[5] FOOTNOTES: [2] _Active and Moral Powers_, ii. 312.
