Fish swim, birds fly, and people feel
"Emotions are part of our genetic heritage. Fish swim, birds fly, and people feel. Sometimes we are happy, sometimes we are not; but sometimes in our lives we are sure to feel anger and fear, sadness and joy, greed and guilt, lust and scorn, delight and disgust. While we are not free to choose the emotions that arise in us, we are free to choose how and when to express them, provided we know what they are. That is the crux of the problem. Many people have been educated out of knowing what their feelings are. When they felt hate, they were told it was only dislike. When they were afraid, they were told there was nothing to be afraid of. When they felt pain, they were advised to be brave and smile. Many of us have been taught to pretend to be happy when we're not."
