Please allow me to answer you in a philosophical way, because I am not a writer and can't understand his wishes. The downward comparison in life is to compare with people who are worse than us in life, so that we can be satisfied in life. The meaning of upward comparison at work is similar to the previous one, that is, comparing with people who are more successful than us at work, which will make us more motivated and let us know that we still have a lot to work hard for!
