Don't keep looking back all the time， you're bound to get depressed. And all right， you can't do your job as well as you used to. But it's the same for all of us， see? We've all got to put our feet up at some point. Look at me. Been happy as a lark since the day I retired. All right， so neither of us are exactly in our first flush of youth， but you've got to keep looking forward.
—The Remains of the Day， Kazuo Ishiguro
不要总是回头看，你一定会沮丧的。并且，虽然你不能像年轻时那样，把工作做得尽善尽美，但这对我们来说都是一样的，明白吗？总有一天，我们都要歇歇脚。你看我，自打我退休那天起，我就像只百灵鸟一样欢欣雀跃。好啦，即使我们都不再青春年少，但人总要向前看。
——《长日将尽》石黑一雄
