When you smile, the whole world smiles with you. When the man told the fish a beautiful and touching story, the man shed tears, and the fish also shed tears, because they were both moved by the story. For the bird, happiness is listening to the bells of the bell tower; for the frog, happiness is being able to sing in all seasons; for you, what is happiness? "Happy" and "unhappy" all depend on what you think. If you think that way, you can be happy; if you think that way, you can be unhappy. If you want to make yourself a happy person, make yourself a happy person.
