It's quite natural to hear the word "sacrifice" and immediately think of having to give something up that you like. You hear of people making sacrifices in life such as sacrificing leisure time to work more hours to earn more money, or sacrificing a weekend break to be able to pay the rent, or other such things of that nature. But there is more to this circumstance than meets the eye and when you learn how to really make proper use of sacrifice, you will discover there is a great deal to be gained. The first thing you need to do is to change your impression of what exactly sacrifice is. Don't think of it as having to lose something, but instead think of it as sacrificing something of a lower nature in order to gain something of a higher nature. The chess player understands this concept well. When playing the game, a certain piece will be sacrificed in order to win the game, or to gain an advantage over the other player. They give up, say a bishop in order to be able to take the opponent's queen in several moves further along.
