Cultivating other-centeredness is central to happiness. It is the ability to think of others. Other-centeredness is in stark contrast to self-centeredness. Self-centeredness is when you are only thinking of yourself. Buddhists commonly believe that the more you think of others, the happier you are. In other words, it is skillful to cultivate other-centeredness even if it is for your own personal benefit or happiness.
