        Let’s say you start to brain storm a list of all the emotions you ever experienced. Just for fun, try it now.

　　What’s on your list? Chances are, you included things like: happy, sad, excited, angry, afraid, grateful, proud, scared, confused, stressed, relaxed and amazed. Now sort your list into two categories: positive emotions and negative emotions.

　　Feeling both positive and negative emotions is a natural part of being human. We might use the word “negative” to describe more difficult emotions but it does not mean those emotions are bad or we shouldn’t have them. Still, most people were probably rather feel a positive emotion than a negative one. It’s likely you prefer to feel happy instead of sad or confident instead of insecure.

　　What matters is how our emotions are balanced. How much of each type of the emotion positive or negative we experience.

　　Negative emotions warn us of threats or challenges that we may need to deal with. For example, fear can alert us to possible danger, it’s a signal that we might need to protect ourselves. Angry feelings warn us that someone is stepping on our toes, crossing a boundary or violating our trust. Anger can be a signal that we might have to act on our own behalf.

　　Negative emotions focus our awareness. They help us to zero in on a problem so we can deal with it. But too many negative emotions can make us feel overwhelmed, anxious, exhausted or stressed out. When negative emotions are out of balance, problems might seem too big to handle.

　　The more we dwell on our negative emotions, they more negative we begin to feel. Focusing on negativity just keeps it going.

　　Positive emotions balance out negative ones, but they have other powerful benefits, too. Instead of narrowing our focus, like negative emotions do, positive emotions affect our brains in ways that increase our awareness, attention and memory. They help us take in more information, hold several ideas in mind at once and understand how different ideas relate to each other.

　　When positive emotions open us up to new possibilities, we are more able to learn and build on our skills. That leads to doing better on tasks and tests.

　　People who have plenty of positive emotions in their everyday lives tend to be happier, healthier, learn better and get along well with others.
