"Life sometimes becomes so selfish that it wants everything and while trying for everything, we miss something that is worth everything!"
Selfish Defined: Selfishness denotes an excessive or exclusive concern with oneself; and as such it exceeds mere self interest or self concern. In that it necessarily connotes a disregard for others, it is beyond the act of placing one's own needs or desires above the needs or desires of others (self interest). Psychologist and primatologist Frans de Waal takes issue with those who equate "selfishness" with "self-serving." He argues that "Selfishness implies the intention to serve oneself, hence knowledge of what one stands to gain from a particular behavior".
Selfishness is the opposite of altruism (selflessness).
