Self-interest refers to actions or decisions that are intended to benefit oneself, without considering the interests of others. It is driven by personal desires and goals, often prioritizing one's own wellbeing over the wellbeing of others. Self-interest can manifest in various ways such as seeking financial gain, pursuing power or prestige, or focusing on personal happiness at the expense of others. While self-interest is often seen as a negative trait, it is also an essential part of human nature and plays a role in motivating individuals to achieve their goals.
