I searched on the in the internet “What is the most joyful thing in all the world” and I found two articles. One written by KB which focuses on inner self and the other one by Baker International focuses on habits of joyful people.
KB says
If you want to be joyful, you must learn to mimic these qualities of spirit until they become second nature. In time you’ll realize that joy is not something you “obtain”; it’s something you reveal. The truth is that joy already exists within you; it’s your natural state of being. You’re simply in the process of polishing your mind and heart so that your true joyfulness can shine through.
