This may sound simplistic, but if you want to be happy, then decide to be happy. One way to help with this is to think happy thoughts. (That’s right, just like Peter Pan told Wendy!) When you choose positive thoughts over negative ones, you are more likely to develop an optimistic outlook on life. Positive people generally have higher levels of optimism and life satisfaction, plus they live longer. And here’s some good news—even if you aren’t normally a happy person, thinking happy thoughts is a skill you can learn. Work on being an optimist: choose to think positive thoughts and see the proverbial glass as half full rather than half empty. The next time you’re driving and someone cuts you off, for example, resist the urge to respond with anger, which can clamp down your blood vessels and increase your blood pressure. Instead, stay positive and let your anger go. Keep that positive vibe going no matter what you’re doing. The more frequently you choose to be happy, the happier you will be.
