There is sunshine even on an overcast day.
Here's the thing:
The sun is always there. During a rainy day, when it's pouring buckets and you're considering gathering two of every animal before building an ark? It's behind the cloud cover. Even when it's snowing, there is sunshine.
There is sunshine in the darkest, pitch-black room where there are no windows.
There is sunshine in the crevices and caves of the deepest parts of the Earth.
There is sunshine in the darkest parts of war-torn countries when it looks like there is no hope.
There is sunshine when a baby is born, crying and screaming, and when that elderly person takes their final breath.
Remember that. There is sunshine, and where you take it, it will always go. The sunshine is inside, and no one can ever take it away from you.
