Dr. Robin talks about a Native American tribal story in which a man struggles with two dogs that live inside of him: one is mean and evil; the other is good, noble and righteous. The question of what's right versus what's wrong arises when he has to decide which dog to feed the most: the good one or the evil one?

We must acknowledge that we all have good and evil living within our minds, Dr. Robin says. The thoughts that you nurture and you pay attention to are the things that grow. "The thing that you focus on, it is that which grows," she says. "Starve that thing that's trying to tear you down and take you down." 

We all feed destructive thoughts within us, Dr. Robin says. "If you've been feeding the negativity in you, if you've been feeding depression—the dog that keeps you living in fear—then that's the dog that will win," she says. "But if you begin to feed the dog in you that says all things are possible, if you need courage and you ask for it, that is the dog that will win and be victorious. Feed the dog in you that helps you live your very best life."
