College experience:
Four years of college，For me, it is a process of finding myself。My friends often tease me that I lived the life of one of the three types of people in college，Baoyan、Fallen、Postgraduate entrance examination。I really like Gems’ line “I once stepped on the top of the mountain，Also hit rock bottom，Both have benefited me a lot。”
Freshman year，Fortunate to have the guidance of fellow seniors，He gave me a detailed introduction to the concept of "research research"，Tell me what I should do to prepare for professional courses and scientific innovation。The senior patiently told me what knowledge I should learn。So I spent my freshman year studying for exams and preparing for scientific innovation，Get up at 6:30 in the morning，Lie down for a while in the library at noon，Go back to the dormitory to change the program at night，Soldering circuit board。To be honest，Science and technology innovation brings me much more challenges and frustrations than exam classes，You can listen carefully in the exam class，Take notes，Do the questions well to get good grades，But learning programming languages and hardware errors really make me confused a lot of times，Especially for a novice like me。Although most of my science and innovation achievements during my freshman year were only a few school-level third prizes，But I gained a lot of knowledge，Tempered my patience，I still feel very precious to this day！That’s it，Under a high degree of self-discipline and strict work and rest，Not only did I save my gpa，Also won the provincial second prize in mathematical modeling、Provincial First Prize in Mathematics Competition、Provincial first prize for the Internet of Things and other scientific and technological achievements that I am satisfied with，I also successfully won the national scholarship。
But，Time is like a low-pass filter，Filters out the high-frequency components of passion in our lives，Even a square wave，It will also be smoothed out in the end，Lost its edges，Become smooth、mellow。
Sophomore year，I gradually realized the pleasure of being unconstrained and the joy of gradually indulging myself under academic pressure，I also made a lot of mistakes，Under the long-term self-blame and heavy blows，My mentality is also stronger，My biggest feeling at that time was: I really wanted to change，But a little weak，Maybe，I'm waiting for an opportunity...
The night after the final exam of sophomore year，I know I failed the exam，I didn’t study well，Science and technology innovation is also abandoned，Depressed, I found my academic advisor when I was a freshman，I am very grateful that my academic advisor noticed me when I was a freshman，Believe in my ability，He passed the postgraduate entrance examination and entered Tsinghua University for postgraduate study，So he encouraged me to follow his path。If you say "Life is about setting a general goal for yourself，Then keep working hard for it”，Then for me 99% of the efforts are rational，The 1% of choices are very rational，So emotional that once I make a choice，It’s hard for me to change。
The first semester of my junior year is the day when I fight against bad habits，This day is really unforgettable，Good habits and bad habits keep repeating，Let me start to face the twists and turns of "change"，Reciprocity。With patient efforts，After one semester，I have developed good study habits again，The self-discipline at this time is completely different from that in high school and freshman year，I started to listen to my true inner thoughts，Try to do many things that interest you within the framework of self-discipline，No longer straining yourself，I feel more and more that the process of hard work is really interesting，Although it is ultimately for a specific result，But the process is much more impressive than the result，I have become enjoying the present。
Second semester of junior year，It’s time for postgraduate entrance examination students to start struggling，I am no exception，Due to introversion，I have not participated in any student organizations or societies in my university，The circle of friends is very small，No news on WeChat or QQ，I rarely take my mobile phone out to study，I really enjoy this kind of life without social pressure under the framework of self-discipline: studying with fellow students，Laughing together on the way to the canteen，Go back to the dormitory and chat happily with your roommates，Go to Lingxiucheng to watch a movie on Sunday afternoon，The anxiety of always looking at the phone when not studying，There is no guilt caused by playing games。The second semester of junior year and the following summer vacation are relatively relaxing in my opinion，This ease does not mean that there is little learning pressure，It means the state of mind is very relaxed，This is not only due to the companionship of fellow researchers，Thanks also to the fact that during the winter vacation at the end of the first semester of my junior year, I had completely figured out what kind of life I wanted to live in the next year，Therefore，Before starting a new life journey，Be sure to think clearly about what kind of mentality and state you want to spend next，Otherwise, it is easy to fall into the embarrassing situation of self-contradiction。
First semester of senior year，Once September enters，All postgraduate entrance examination candidates will suddenly feel the tightness of an arrow being pulled full，My daily study time has also been extended from 7-8 hours to 10 hours，There are more and more people in the library，The tense atmosphere becomes more intense，Attitude is really important at this time，How to continue to maintain your review rhythm and move forward steadily in this atmosphere，I think this is the core issue that needs to be solved during this period。At that time, my mentality was just to try my best，So what is trying your best: squeezing in more time，Maintain higher efficiency to study。To do this，Need to continue to maintain self-discipline，Get up on time，Lunch break on time，Go to bed on time，Don’t look at your phone more，Don’t think too much about useless things。When I changed my goal from being admitted to graduate school to completing these processes，This problem will be solved。
Cause of the epidemic，Need to prepare for the postgraduate re-examination at home，Too long front，Let the review plan change again and again，Ten professional courses take turns to attack，Making people more anxious。Review at home，It is completely different from preparing for the initial test，Working alone means you need stronger self-discipline，It is especially important to balance the relationship between housework and studies，Many times you cannot study at home during the day，The biological clock gradually turns into studying at night，Sleeping during the day，After persisting for more than four months，2:00 pm on May 15th，Entered the interview room on time，After more than twenty minutes of asking professional questions，Although some questions are not answered well，But I still have a clue in my heart，More than four months of hard work has paid off，The postgraduate entrance examination means the more you pay，The more you gain。The morning of May 17th，I received a call notifying me of my proposed admission，Put down the phone，I feel very calm，Thinking of all the setbacks encountered in the past few years，I only feel grateful，It is these setbacks that have tempered me，Let me understand what kind of life I want to live: working hard may not stop you from working hard in the future，It takes you to a place that requires more effort，The high-spirited fighting attitude is hard work，But very fulfilling and meaningful！
Message: Four years of college，You will definitely encounter many setbacks and hardships，Experience doubts about yourself，I hope you can relax when going through this，Enjoy the process of defeating them，You will be particularly happy after the rain and the sky clears！
