What is happiness?

Why is that when we are happy things are easy to deal with and it all fits into place? But when sorrow is upon us, we can’t wait for it to end. What do you do when happiness seems to have left your life?
Anyway “happiness is always there in the back of our mind, but we’re so caught up in our sorrow that we don’t pay attention to it.” It’s true isn’t it? When we’re overwhelmed by pain or sorrow we tend to forget the little stars that are shining for us day and night, sparkling around us like little butterflies bringing us laughter and smiles every day.The gift of happiness is one that we all have the ability to give to someone. It’s cheap to give, but very weighty in it’s value.
