This is sane philosophy.

Not ignoring the danger, pooh-pooing it, scoffing at it and refusing to recognize it, but calmly, sanely, with a kindly heart looking at possible contingencies, preparing for them, and then serenely trusting to the spiritual forces of life to control events to a wise and satisfactory issue.
Can you suggest anything better?
Is not such a course immeasurably better than to allow himself to worry, and fret and fear all the time?
Practical precaution, _taken without enmity_--note these italicized words--trustful serenity, faithful performance of present duty unhampered by fears and worries--this is the rational, normal, philosophic, sane course to follow.
Another great source of worry is _our failure to distinguish essentials from non-essentials_.

What are the essentials for life?
For a man, honesty, truth, earnestness, strength, health, ability to work, and work to do.

He may or may not be handsome; he may or may not have wealth, position, fame, education; but to be a man among men, these other things he must have.

For a woman,--health, love, work, and such virtues as both men and women need.
