"To 'sacrifice' is to make sacred. In the long history of devotion, people made sacrifices to honor the Most Worthy, giving up something of great value--a goat, a rooster, sometimes a son. It is exactly this renunciation of self-interest that brings a person into closer relation to the divine.
"So a better way to think about sacrifice is to ask, What ways of acting will reduce my fixation on self-gratification, and so bring me into closer relation with what is Good-in-itself, the Earth, the unfolding of life?"
