Smile.

When things get rough,
Smile.
When people knocked you down,
Smile.
When you're as invisible as a wallflower,
Smile.
When you know that you don't stand a chance,
Smile.
Because sometimes-
It helps.
And someday,
Or anytime now,
Or sometime next week,
things will be looking up,
And you'll be someone's wonderwall,
Which is better than anything else in the world.
