There is a Cherokee parable about two wolves fighting inside every person.
One is Evil—it is anger, envy, 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 asks the grandfather, "Which wolf wins?"
The grandfather replies, "The one you feed."
We all face internal battles. When things get difficult, it is incredibly easy to feed the fear wolf with self-doubt and negativity.
You have to actively choose to starve the fear and feed the hope. The mindset that ultimately dictates your future isn't determined by chance—it is determined by the one you choose to feed.
