一次,老师从家乡返回,第二天我去拜访。聊着此行见闻,他突然惆怅,说自己老了。我当他是一时心血来潮,好奇他为什么这么说。老师说:“我一向如此,内心想到什么事,马上就要动手做,从来不会等等再说。每天早晨,不管几点,只要睁眼,马上起身。但是,今天醒来后,我竟然想,再睡一会儿吧。这在以前从来没有过,所以,我猜,是不是老了。” Once, the teacher returned from his hometown and visited the next day. Chatting with this trip, he suddenly melancholy that he was old. I was when he was a whim, curious why he said so. The teacher said: “I have always done this, and when I think of something inside myself, I have to do it immediately and I will not wait for it. Every morning, no matter what time it is, I just open my eyes and immediately get up. Think, sleep for a while, which has never been before, so I guess that’s not old. ”
