Because to be human is to experience all emotions. In emotions, it is best to be wealthy. But it takes maturity and a healthy well-being to achieve that skills acknowledging all human emotions rather than choosing only what is best for the situation. Every emotions we encounter co exist to each other, hence, we must know how to accept it and sit with it for us to process them in healthy way. Sadness and joy, a full contrast, and an opposition. But what happens when we accept that the two should be put in the same room to breathe? We understand life and our emotional experience completely. And perhaps, we won't be only labelling joy as happiness or sadness as turmoil but simply experiences that make us human.
