The thing about kids is that they express emotion. They don’t hold back. If they want to cry, they cry, and if they are in a good mood, they’re in a good mood. Eddie Murphy
Even as an adult I have mood variations. What sets me in a down mood is allowing my mind to enter into commentary with thoughts that are not reality. When I’m able to release those thoughts, letting them drift off and stay present, I experience greater serenity. I’m therefore in a better mood.
