Which do you feed?

An old Cherokee told his grandson, "My son, there is a battle between two wolves inside us all. One is Evil. It is anger, jealousy, greed, resentment, inferiority, lies, & ego. The other is Good. It is joy, peace, love, hope, humility, kindness, empathy, & truth." The boy thought about it, and asked, "Grandfather, which wolf wins?" The old man quietly replied, "The one you feed".
