Smile, it's all that i need

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 fear and sorrow,

Smile and maybe tomorrow,
you'll see the sun come shining through for you

Light up your face with gladness,
Hide every trace of sadness,

Although 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 worth-while,
If you just smile
