Self-centeredness is a fundamental factor for survival; from this perspective, it is not necessarily bad. However, if a person's self-centeredness is too strong, always feeling that one is right, with an insatiable desire for gain, or feeling arrogant or self-disparaged, then it will be very difficult to be happy. 自我中心原是一種生命的動力，不見得是壞事，但是 如果自我中心太強，經常自以為是、貪得無厭、傲慢 或自卑，自己是快樂不起來的。 - Master Sheng Yen
