Peace starts with a smile. Smile to people around you. When you smile, you look nicer and you are friendlier. It takes twice as many muscles to frown as it does to smile.

Start smiling now. Spread the peace around you.

Five enemies of peace inhabit with us – avarice, ambition, envy, anger,
and pride; if these were to be banished, we should infallibly enjoy
perpetual peace.
