This speech really affected me a lot. In this speech, he talked about three stories. Each of them has some good phrases for me to learn. He said your time is limited, so don't waste it. Actually, I can utilize it more efficiently. But I usually waste almost all of it. It is a problem that annoys me for a long time. But after listening to the speech. I suddenly realize how precious it is. People don't what they have got until they lose it. So I start to ask myself if today is the last day. Do you satisfy it? And arrange my schedule.
