Too good people are easily envied by others. And jealous people tend to find other people's shortcomings. What's more, there are no perfect people in this world. The more prominent the advantages, the more prominent the disadvantages. Therefore, people should not be too nice.
Too good people often can't get along, because people don't want to be with too good smart people. They have no appreciation and a sense of inferiority. Too good people tend to be lonely. Imagine that if others are inferior to you everywhere, they naturally don't want to stand with you. That's not to mention the jealous ones. Their destructive power is amazing.
Some truth is obvious, but people always turn a blind eye. Perhaps people don't realize it, but there is a phenomenon: people often have a gloating attitude towards the destruction of the strong, but always have unrestrained sympathy for the weak. It is this mentality that requires people to learn to converge their own light.
