Sacrifice is being willing to give up something good for something better.
Life is full of boundless possibilities, but in order to transform a possibility into a reality we have to choose -- sacrificing the many in order to attain the one. Nothing is gained without something relinquished.
Sacrifice has meaning only in the context of a goal, dream or mission. In pursuing these, we often face obstacles which require us to forfeit physical or emotional comfort in the service of something that matters more. Often, the greater the dream or vision, the greater the shared sacrifice required to attain it. Sacrifice is easier when we stay focused on what we are choosing rather than what we are giving up.
