The age of 25 is a special time in life. It is the beginning of the youthful period of life and the beginning of the physical and psychological farewell to the role of a student. Wang Erjun, a student who graduated from a second-rate school two years ago with a non-ace major, is now working as a customer service assistant for an Internet company. Wang Er's 25-year-old: love, lingering in blind dates again and again; work, struggling with insomnia at night worrying about unemployment; life, simple and complicated in the drowsiness; days, slipping away in a daze. I have searched countless times how other people spent their 25s, but I found that no matter which way of life I lived, I couldn't directly apply it to myself. I have comforted myself more than once. In fact, ordinary people like us are where most people end up. But looking back on my previous days, I found that apart from knowing that I was one year older, I had completely forgotten those stories that belonged to me. I began to be afraid of the passage of time, and even more afraid of recalling the mediocre self in the passage of time. This article records every day of Wang Er's 25-year-old life, work, life, love, and academic trends, in order to pay tribute to my 25-year-old.
