There is an old Cherokee tale tells of a grandfather teaching life principles to his grandson. The wise old Cherokee said,
"Son, on the inside of every person the battle is raging between two wolves. One wolf is evil. It’s angry, jealous, unforgiving, proud, and lazy. The other wolf is good. It is filled with love, kindness, humility, and encouragement. These two wolves are constantly fighting."
The little boy thought about it and said,
"Grandfather, which wolf is going to win?"
The grandfather smiled and said,
"The one you feed."
