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 worthwhile
If you’ll just
Smile

I'd never thought I would see the day I put the lyrics of a song on my blog.
