"If you are happy, notify your face."

My mother used to say this to me as a child. When I was sad or frustrated, I hated hearing this common phrase, because it felt hard to smile when I wasn't happy. At other times in my life when I was learning how to feel my emotions for the first time, I didn't want to bypass my true feelings and fake a smile. I had done that for too long. But now as an adult, who understands the power of a smile, I understand the wisdom beneath my mom's words.
