Many people find it easy to feel pain and internal conflict because they overestimate the existence of "humans" and forget that everyone’s most fundamental nature is animalistic. The instinct of animals is to be driven by desire, maximize benefits, and minimize risks. The relationships between people may seem calm on the surface, but impulses, desires, and interests are always surging in the background. If you imagine people to be too kind and relationships to be too pure, then even a small calculation or indifference from reality can leave you utterly disappointed. True clarity is not about living in an idealized world, but about daring to acknowledge and confront the darker sides of human nature and relationships. Only in this way can you avoid being consumed by it and stop getting hurt repeatedly due to the gap between expectations.
