“Movement is the essence of life.”

“The thoughts that occur to me while Im running are like clouds in the sky. Clouds of all different sizes. They come and they go, while the sky remains the same sky always. The clouds are mere guest...”

“Running cleared the day's cobwebs from my mind and focused my thinking, and gave me time and space to sort out anything that was bothering me, or to detach and think of nothing at all.”

“When Douglas walked, his mind ran, when he ran, his mind walked.”
