What I Talk About When I Talk About Running

Lovely memoir with an inspiring take on exercise, specifically, a running life. This book was insightful and fun but it also talks about the downsides of his running life. His failures and pains. And what happens in his mind when he runs:

???The thoughts that occur to me while I???m 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 guests in the sky that pass away and vanish, leaving behind the sky.???
