One's perception determines what they can see. If you view the world with a kind eye, it's easy to overlook the complexity of human nature.

In the social circles of ordinary people, the probability of encountering someone who is either foolish or malicious is actually not low. Foolish people fail to see your kindness, while malicious people exploit your goodness. The result is that your energy and benefits are gradually drained, ending up in a thankless situation. We always believe that sincerity begets sincerity, but the reality is, not everyone has a heart.
