You can not make everybody happy, but you can make someone happy because you're happy. Not all smiles mean happiness. What is hidden behind a smile can not always be seen. The easiest way to be happy is to smile. Because a smile is the beginning of happiness when sorrow greets.
Make our hearts always peaceful, so we can make ourselves happy and happy others. Listen to the voice of your heart, not the conscience of others. Because who is responsible for your happiness is yourself.
