I'm in tears. I'm a postgraduate student in China and I'm already in my second year of study. But I'm very depressed every day. There's no progress, my work is not going well, I have no time to exercise, no time to play, and I even often stay up all night doing experiments, but the progress of my experiments is still zero. I found this by chance while searching for keywords in the literature. It took me a few minutes to finish reading it. I can only say that I'm deeply touched. I'm already 24 years old. My peers are all getting married, buying houses, and taking care of children. But I'm thinking about what to eat next and what posture to stand in at my laboratory desk to be more comfortable. What a fragmented world The thought that the world is so big but I have to stay in the laboratory doing experiments makes me feel bored I was deeply touched when I clicked in by accident. It felt like we were neighbors at the ends of the earth. Maybe after I posted the comment and threw myself back into the experiment, I wouldn't be able to click on this website again. But I still want to share my thoughts. Let my ideas briefly appear on the Internet and then be eroded by its rapid iteration
