Quote

In chess, sacrifice means giving up a piece of lesser value (such as a pawn) in order to capture a piece of greater value (such as a queen). Imagine playing chess from a self-sacrifice perspective. The game would be over in a hurry, with the self-destruction of the self-sacrificer. Likewise, in real life, the self is the greatest value anyone has. consequently, any sacrifice of self, is by definition, self-destructive.
