        I took the exam today 《 Digital circuit and logic design 》, In the course of the exam , There is a situation ： A female classmate behind me called my name , And ask me the fourth question, what is the counter , I'm really a little stunned , Although I often see you in class on weekdays , But we haven't communicated . Besides, I'm used to skipping alone on weekdays . She asked , I also want to answer , But I looked at the title , But I don't know how to answer . Although I don't know whether she asked multiple-choice questions or big questions , But the truth is , I'm not very good at both questions . Average academic performance , Usually I don't seem to spend money on my study 50% The energy of , Because I was still affected by some bad habits . My hard-working grades , For some people , A cheat sheet gets higher grades than you . If it's an individual phenomenon, that's good , But is that really an individual phenomenon ? It was almost the last one to hand in the exam , Whenever I see that 30 minute , A person who handed in his paper when he was a child , I couldn't help but cast a surprised look . Finally, there is time left for yourself , I always feel ants crawling in my heart . I don't know how to treat , I always feel that my efforts in learning are so worthless . Although two years , But I'm still not used to this phenomenon . I failed to answer the question of the female classmate this time , I'm also reflecting , Want to break through the dilemma , Why not start with learning , Whether your professional ability is strong enough .

      Today, I have a question :“ Why should one work hard , How much effort do I have to make in College ”. Why should one work hard , From primary school to high school , Do I really want to understand this problem ？ Try to get good grades in primary school , Just to be parents , A good child in the eyes of teachers . I worked hard in junior high school to get a good high school , In high school, I worked hard to get into a good university , What did you work hard for in College ？ Go to college , I have been regarded as the reserve army of society . Trying hard in college is not to find a good job in the future , For more choices in the future ？ And primary school , Junior high school , Work hard in high school , In essence, it is for a good job in the future . But the efforts in college are crucial , It's like walking a hundred miles, half a 90 , It seems to be approaching the destination , Once relaxed , All these years of efforts have been destroyed . Although life is like a marathon , But no one can deny 20~30 Years old is the best time to struggle . But I don't understand the characteristics of this age , I'm confused at this age , Ignorant , There is loneliness . The only way is to boil , Struggle to get ahead , You win . As for how much effort you have to make in College , I didn't think about it at the beginning , Now I see . How ambitious are you , Just try your best ！
