Every man lives in two realms: the internal and the external. The internal is that realm of spiritual ends expressed in art, literature, morals, and religion. The external is that complex of devices, techniques, mechanisms, and instrumentalities by means of which we live.
A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be your constant companion of your walks.
There is much pain that is quite noiseless; and vibrations that make human agonies are often a mere whisper in the roar of hurrying existence. There are glances of hatred that stab and raise no cry of murder; robberies that leave man or woman for ever beggared of peace and joy, yet kept secret by the sufferer --committed to no sound except that of low moans in the night, seen in no writing except that made on the face by the slow months of suppressed anguish and early morning tears. Many an inherited sorrow that has marred a life has been breathed into no human ear.
With memory set smarting like a reopened wound, a man's past is not simply a dead history, an outworn preparation of the present: it is not a repented error shaken loose from the life: it is a still quivering part of himself, bringing shudders and bitter flavors and the tinglings of a merited shame.
