An old Cherokee is teaching his grandson about life:A fight is going on inside me, he said to the boy. It is a terrible fight and it is between two wolves. One is evil - he is anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego. The other is good - he is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion, and faith. This same fight is going on inside you - and inside every other person, too.The grandson thought about it for a minute and then asked his grandfather,Which wolf will win?The old Cherokee simply replied, The one you feed.

The mean dog fights the good dog all the time. When asked which dog wins, he reflected for a moment and replied, The one I feed the most. On Other Peoples Expectations: The only man who behaved sensibly was my tailor; he took my measurement anew every time he saw me, while all the rest went on with their old measurements and expected them to fit me.
