Smiles can be found even in sadness

I heard a beautiful song today called "Smile" and I really liked it even though I thought at first it sounded sad. I think it shows how even in sadness there can always be a spark of happiness that helps get through whatever happens. I find that as long as I can still smile (even if it's only a small smile) I feel like things will be all right. Even if things don't work out as I might plan or hope, the point to me is that things do work out and with that in mind I can't help but smile.
