I think: at some point in life, people he knows will die more than live. At this time, you will refuse to accept other faces and other expressions: every new face you meet will be printed with traces of the old mold, and you will put on corresponding masks for them. Abundant energy and tenacious determination have created many miracles. There is no such thing as failure unless you stop trying. Sometimes others may not care about you, but you can't help caring about yourself. Go by yourself, even if it is bumpy, you must live by yourself. Refusing to admit failure is to challenge yourself; Admitting failure is to accept yourself correctly, see a broader side of the world and remain humble.
