Happiness is built on sorrows, be it of our own or the rest of the world. Why? Without going through heartache moments and troubled souls, we would not have understand the meaning of happiness; without knowing how the others have suffered in order to live, we would not have known we are actually living in the happiness which many are asking for. When there are no problems, there would not be the questions and brain storming on working things out; when there are no negative emotions, the positive ones would not be reflected. Certainly, this is merely one way of saying it, as there could be the others depending on our perspectives.
