Selfishness means thinking only of yourself. No matter how others feel. It can also be summed up in that sentence: I would rather lose the world than the world lose me. This is the ultimate in selfishness. Selfishness means trying every means to get what you want, never caring about other people&;s feelings, only thinking about yourself, having no affection or friendship, never thinking of helping others, and ignoring others when they are in trouble, thinking that they will never need help from others.
