Unselfishness is a virtue or quality characterized by a lack of selfishness or concern for oneself and a genuine consideration for the well-being and interests of others. It involves putting the needs and welfare of others before one's own desires or concerns.
The phrase "thinking less of yourself" typically refers to having a humble and modest approach to life. It means not excessively valuing one's own importance, achievements, or possessions. This perspective can be a part of unselfishness, as being humble and not overly focused on oneself can make it easier to empathize with others and be more willing to assist them.
On the other hand, "thinking of yourself less" implies that you are actively redirecting your attention away from your own wants and needs and prioritizing the needs of others. It involves being considerate and compassionate towards others, even to the point of sacrificing your own interests for their benefit.
Both interpretations are closely related and can be seen as aspects of unselfishness. Being unselfish involves an attitude of empathy, kindness, and putting the greater good above personal gain. It doesn't necessarily mean neglecting one's own needs entirely but rather finding a balance between self-care and caring for others.
In summary, unselfishness can be understood as a combination of thinking less of oneself in terms of ego and self-importance and thinking of oneself less in terms of prioritizing others and their well-being.
