Smile, though your heart is aching. Smile, even though it's breaking.
When there are clouds in the sky, you'll get by if you smile.
Through your pain and sorrow, smile, and, maybe tomorrow, you'll see the sun come shining through for you.
Light up your face with gladness, hide ev'ry trace of sadness, altho' a tear may be ever so near, that's the time you must keep on trying.
Smile, what's the use of crying? You'll find that life is still worthwhile, if you just smile.
