The one you feed!

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