From “Footpaths” by John Burroughs

It is not walking merely, it is keeping yourself in tune for a walk, in a spiritual and bodily condition in which you can find entertainment and exhilaration in so simple and natural a pastime. You are eligible to any good fortune when you are in the condition to enjoy a walk. When the air and the water taste sweet to you, how much else will taste sweet! When the exercise of your limbs affords you pleasure, and the play of your senses upon the various objects and shows of nature quickens and stimulates your spirit, your relation to the world and to yourself is what it should be—simple and direct and wholesome. The mood in which you set out on a spring or autumn ramble or a sturdy winter walk, and your greedy feet have to be restrained from devouring the distances too fast, is the mood in which your best thoughts and impulses come to you, or in which you might embark upon any noble and heroic enterprise. Life is sweet in such moods, the universe is complete, and there is no failure or imperfection anywhere.
