I haven't read all the posts but I came across this interesting proverb and I remembered seeing this topic. Hope it helps!
There is an old American Indian proverb about a Cherokee chief who is teaching his grandson about life, and he says:
"There is a fight going on inside me. It is a terrible fight and it is between 2 wolves. One wolf is evil --- he is self-pity, envy, regret, resentment, anger, self-indulgence, ego. The other wolf is good --- he is love, compassion, hope, kindness, peace, humility, generosity."
The old chief went on to say, "This same fight is going on inside you. And it is going on inside every other person as well."
The grandson seemed deep in thought for several minutes, and then he asked: "Grandfather, which wolf will win?"
The old Cherokee chief replied: "The one you feed."
