It was almost two o'clock in the middle of the night when I came out of my dormitory to the library of Oxford University. I met an undergraduate student, Alvin, with a box of snacks in his hand. We talked briefly. He was a medical undergraduate, and now he is a freshman. Because I was about to take the exam, I had to go back to the library to continue my study. I saw the serious expression on his face, so I quickly said goodbye to him. When I went to Kent University in 2002, it was like this before I took the exam. The same expression, at that time for more than a month without shaving, learning every day until midnight, sometimes an all-night. The road to genius is usually paved with hard work and sweat. If you want to succeed, you must pay the price of extraordinary people. It's 2:13 a.m. at Oxford University. 2:14... Treasure every minute, every second... 2:15...
