Be optimistic!
Don't you be a grumpy
When the road gets bumpy
Just smile
(Smile and be happy!)
Your troubles can't be
As bad as all that
When you're sad as all that
No one loves you
Be optimistic!
Don't you be a mourner
Brighten up that corner
And smile
Don't wear a long face
It's never in style
Be optimistic
And smile!
