Two  Wolves
One  evening an old Cherokee told his grandson about a battle that goes  on inside all people. He  said, "My son, the battle is between two "wolves" inside us all. 

One is Evil.

It is  anger, envy, jealousy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego.

The  other is Good.

It is  joy, peace, love, hope, serenity, humility, kindness, benevolence,  empathy, generosity, truth, compassion and faith." 

The grandson thought about it for a  minute and then asked his grandfather,

"Which wolf  wins?"

The old Cherokee simply replied,  "The one you feed."
