God wants you to be happy. There is something good inside of you that tells it is just right to be so. Look around ! Your family, relatives and friends, they all want to see you glad. At home, in the neighborhood, in school, in working place, in the church, everywhere, it is fulfilling to watch a life full of joy.
Here is a video uploaded by VideoJug on 15 Feb 2008 showing how to find happiness in seven simple steps.
The Bible says in Ecclesiasticus 30 22-27:
 Give not up thy soul to sadness, and afflict not thyself in thy own counsel.  The joyfulness of the heart, is the life of a man, and a never failing treasure of holiness: and the joy of a man is length of life.  Have pity on thy own soul, pleasing God, and contain thyself: gather up thy heart in his holiness: and drive away sadness far from thee.  For sadness hath killed many, and there is no profit in it.
