When we are happy, we teach others how to be happy. Happy people love to be happy and to share their happiness. Happiness attracts more of the same. It is the same for all of our emotions.
It is not a game – how to be happy always. We are supposed to have all the feelings we have. It is a choice that we make all the time. Choose some happiness today and you will teach it too. And that will make the whole world a little happier.
