Human nature is like water, shifting with circumstances. When you bring benefit to others, they are kind; when you offer nothing, they become self-centered; when you threaten their interests, they turn cold and harsh.
This truth applies to family, friendship, and love. What we call a broken relationship often stems from a broken flow of mutual benefit. Observe successful business leaders—always busy traveling, rarely at home—yet few of them claim their marriages are failing. Behind every bond lies a foundation of shared interests.
Understanding this doesn’t mean being cynical. It means seeing clearly, so you can be more tolerant and navigate life with calm wisdom.
