We all want to be happy. But we sometimes think of happiness as a thing that happens to us — something we have no control over. It's easy to link the idea of happiness with the situation we're in. We might tell ourselves, "If only things were different, then I'd be happy."
Smiling is contagious. We all have our own battles to fight. Each one of us! And sometimes all a person needs is a smile to reassure them that everything will be OKAY (because it will be). Maybe one smile can reassure that girl who sits beside you in the class, that someone sees her - that someone actually cares. Maybe one smile to a stranger you walk by in town today is all it will take to turn that rainy cloud hanging over him into a bright shining sun.
