It's a simple question, isn't it. But, can you confidently answer it? I was shocked when I first was posed this question because I was unable to answer it. "But I feel sadness, I must know what it is?" I told myself. Humans have very little training in our emotions. But this topic isn't one that needs to be drawn out over weeks and years. This process starts with knowing a few definitions. Once this is established, you will learn a lot about yourself. This is a slow discovery that your interpretation of a situation is "constructing" an emotion that is either useful or not useful. Have you ever labeled the situation incorrectly? Did you construct anger? What happens if you interpreted the situation the way the other person intended, would you have constructed a different emotion? Let's talk about definitions of emotions, and then we move to our motivations, our expectations, our personality traits and our past stories that contribute to the construction of emotions. So.....before looking it up, what is sadness? What is your sadness responding to?
