galvanize

Enthusiasm hard to muster
When the world has lost its luster.
When everything tastes just like dust
You only eat because you must.
If smiles come but ruefully,
Grinning exhausts, truthfully.

But then, surprise! A light blinks on
After you thought all light had gone
And night would reign forevermore,
Sunshine comes knocking at your door.
Time can wound or time can heal.
Either way, changing how you feel.

This time, brave and getting braver
Instead of grim and getting graver.
And galvanized by simple spark
Your raucous laughter shatters dark.
Like a geyser bubbling
Giggles grow, redoubling.

Not to say there's no more sadness
But balanced back again with gladness.
