Spend some time with Nature, too. The people and Nature--they alone
contain the elemental forces. They alone are unartificial,
unexhausted. You will be surprised at the strength you will get from a
day in the woods. I do not mean physical strength alone, but mental
vigor and spiritual insight.

The old fable of Antæus is so true that it is almost literally true.
Every time he touched the earth when thrown, that common mother of us
all gave him new strength; and, rising, he came to the combat as fresh
as when he began.

Learn to know the trees; make friends with them. I know that this
counsel will appear far-fetched if you have never cultivated the
companionship of the woods. But try it, and keep on trying it, and you
will find that there is such a thing as making friends with the trees.
They will come to have a sort of personality for you.

No doubt this is all in your mind. No matter, it is good for you. It
makes you more natural; that means that you are more simple, kindly,
and truthful. What is more soothing and restorative than to stand
quite still in field or forest and listen to the thousand mingled
sounds that make up that wondrous melody which Nature is always
playing on the numberless strings of her golden harp. Learn the peace
which that music brings to you.

In short, cultivate Nature, get close to Nature. Try to get Nature to
give you what she has for you as earnestly as you try to get what you
want in business; and your days and nights will be glorified with a
beauty and strength the existence of which you would have denied
before you experienced their blessings.
