“Remember, you’re the one who can fill the world with sunshine.”
Even when it is grey and rainy outside, it can be warm and bright inside because that light comes not from the sky but from your spirit.
Some people are always gloomy, ready to rain on any parade. Avoid them as they will dampen your spirit. Be around those that can properly reflect your sunny personality and let them light your world.
Make people happy when their skies are grey.
