It might sound a little strange to say that we should be happy at work. After all, it's called work! But we spend more time at our jobs than we do engaged in almost any other activity. If we're unhappy at work, we're likely to feel the effects in other areas of our lives, too. Finding ways to be happy at work not only brings you greater productivity and greater job satisfaction, but will help you achieve greater overall mental, emotional, and physical health.
