A smile can makes a person's day, anybody's day even a stranger's day.
A smile is infectious. Start infecting people with your smile today.
A smile is nature's best antidote for discouragement. It brings rest to the weary, sunshine to those who are sad, and hope to those who are hopeless and defeated.
A smile is so valuable that it can't be bought, begged, borrowed, or taken away against your will. You have to be willing to give a smile away before it can do anyone else any good.
Above all else, if you are tired or feeling low in spirit, give yourself a smile. There is nothing better than to treat yourself to a smile to brighten your day.
