Books" and my food, and summer rain, Knocked on my sullen heart in
vain. If, in short, we have not disciplined ourselves to happiness,
it may well be maintained that we have left undone our highest duty
to our neighbor and ourselves. And he may with good reason declare
that he has solved the greatest problem of life who can proclaim with
Tolstoy, "I rejoice in having taught myself not to be sad!" or with
the Apostle Paul, "I have learned in whatsoever state I am therein
to be content." Much of the secret of happiness is to be found in
Epictetus and Marcus Aurelius and, of course, in the Gospels. Of
modern writers, among the most useful are Stevenson and Chesterton.
See, for example, Stevenson's Christmas Sermon, and J. F. Genung's
Stevenson's Attitude toward Life. Chesterton's counsels are too
sattered to make reference practicable.

Resartm.
