Cheerfulness is special because of how it affects others. It isn’t just something that you feel on your own, it involves expressing positive feelings to those around you.[1] Acting cheerful when you’re really not happy can actually produce the opposite effect in those around you. You may think you are great at faking emotions. But, your body language and facial expressions can reveal your true feelings.[2] By focusing on what you’re passionate about and learning to share this passion with others, you can become more cheerful.
