Happiness

מצָוה גּדוֹלה להיוֹת בּשׂמחה תּמיד It is an important mitzvah to be happy constantly. This very important statement means a lot of things. It serves as the lyrics for several popular Jewish songs and it is the basis of certain philosophies on life, but one thing it does not mean is that being happy is one of the 613 mitzvos.
