an unforgettable conversation The first long conversation between me and my ex-girlfriend is always an unforgettable memory. It was 2014 and I joined a competition which called the championship of Freescale intelligent car and in there I meet a girl who looked peaceful and sweet with long black hair and a pair of big eyes. Which attracted me deeply and I think I can never forget this impression in my whole life. Suddenly I got her name and made friends with her in social network. One night in 2014, several days after I followed her, we had a long conversation and talked a lot about each other. I learned much more about her, her ex-boyfriend, her family and especially the achievements she got. She could play lots of instruments such as guitar, erhu, an ancient Chinese instrument, and piano. Her novels could be published every month. What’s more, she was the champion of the electrical competition of undergraduate in China, which was an important competition in china and I was shocked about this: a freshman got a champion which was so difficult for undergraduate that even junior student cannot get it. She gave me a depth impression again and as a student in the same domain, control science and engineering as her, she did much better than me. And quickly, I got the reason. She worked and studied until 2 o’clock at night every day. Which was amazing for me, in my school. I never meet a person studying hard like her and it is she, gave me a vast view about how to study and how to use the time of university. Although when I meet a competition I would also work day and night but I know I never using my time adequately. But she, a girl, peaceful and sweet, could study hard and did such marvelous achievements. I could never forget the mood at that time, amazed and admiring, and decided to do better than her. I could, liked she could. After that day, I worked and studied harder than before. Every day I got up at 5.30 and slept at 11. Even at noon, I ate my lunch in the way back to my lab from the canteen. And in the next month, I was one of the champions in the RoboCup robot competition.
