An old Cherokee told his grandson,

“My son, there is a battle between the two wolves inside us all.  One is Evil.  It is anger, jealousy, greed, resentment, inferiority, lies and ego.  The other is Good.  It is joy, peace, love, hope, humility, kindness, empathy, and truth.”

The boy thought about it and asked,

“Grandfather, which wolf wins?”

The old man quietly replied,

“The one you feed.”
