Have you ever been greeted by a genuine smile? Of course make the heart happy and comfortable, is not it? How do you feel when your child smiles at you? You can not help smiling back. That's because smiling stimulates our brain's reward mechanism. Just like when we buy something or eat something delicious.

Whenever you are looking for inner peace, try to smile and even laugh at your current situation. This will make you feel better and calm. If you can not smile, you can make a fake smile.

And research has shown that even if you make a fake smile, it can still lift your little load.
