A smile can change your whole day, or at the very least give you a moment of joy.
If someone else is lucky enough to catch you in that moment, then BAM, the joy has been spread.
It's that simple.
Even if you aren't happy, even if you don't want to, just give it a try.
You never know what might happen.
