Pain is inevitable. Suffering is optional. Say you're running and you think，“Man， this hurts， I can't take it anymore.“ The “hurt“ part is an unavoidable reality， but whether or not you can stand anymore is up to the runner himself.

——What I Talk About When I Talk About Running， Novelist， Haruki Murakami

痛苦難以避免，是否受苦卻可以選擇。比方說你正跑著步，突然覺得“哎呀，好難受啊，我不行啦”，這個“好難受”是無法避免的事實，然而是不是果真“不行”，還得聽憑本人裁量。

——《當我談跑步時，我談些什么》村上春樹，小說家
