Happiness increases when we experience more positive emotions throughout the day.Fredrickson , a leader in the field of psychology , identifies 10 positive emotions , including joy , interest , hope , pride , amusement , inspiration , love and so on.How often we experience these positive emotions compared to negative emotions in a day affects not only our mood , but also our physical health.She has discovered that those who have a 3∶1 ratio of positive to negative emotions on a daily basis are happier and healthier. Sadly , most people , even those who consider themselves positive people , are far below that ratio.The good news is that you can learn to increase your ratio of being positive , which leads to greater happiness , health and success. Research shows that by increasing positive emotions , we become more creative , perform better at tasks , and have better relationships.The most exciting finding is that we now have proof that self­generated positive emotions can improve our physical health. Nevertheless , we don’t want to get rid of all negative feelings.Negative emotions are proper and helpful sometimes.It’s appropriate to feel sad about the loss of a loved one.Anger often pushes us into action to improve a situation or correct a mistake.However , if you find yourself waiting impatiently when the driver in front of you doesn’t instantly notice the light turns green , or if you find yourself scolding your kids for laughing too loud while you are on the phone , you are having negative feelings in your daily life too often.Then you should step back and analyze those feelings , and turn them around.
