Kids have to learn from adults. And adults have to learn from kids! Kids can have joy in simple things. They jump and scream. We don't. Kids don't have inhibitions and connect easily. We don't. Why do you think adults have depression? Ok, there could be many reasons. But couldn't one reason be: That we don't move so much, don't play, are serious and don't express our emotions? If a kid is sad or happy, it expresses the emotion. Do we? Next time you are in your car, turn up the music and scream! Play, be silly, find joy in simple things and express your emotions. If you don't know how, then go and observe kids. Maybe they can teach you something as well.
