These are late words and took a long time to write. The "last year" at the beginning was also changed to "the year before last".
Time flows, starting from birth and ending at death. It has a length, so what you want to cherish should be cherished as early as possible, not because you can have it if you cherish it, but because when the length of life is certain, only more time can truly show your inner care. Treat others like this, and do things like this. I also asked myself, so what if I showed it? What's the point? Who knows? Now I think that if I don't do this, life is really meaningless.
