Walking uplifts the spirit. Breathe out the poisons of tension, stress, and worry; breathe in the power of God. Send forth little silent prayers of goodwill toward those you meet. Walk with a sense of being a part of a vast universe. Consider the thousands of miles of earth beneath your feet; think of the limitless expanse of space above your head. Walk in awe, wonder, and humility. Walk at all times of day. In the early morning when the world is just waking up. Late at night under the stars. Along a busy city street at noontime.
