You can do more than you know
Stepping up to face certain kinds of challenges is not optional. This is one of those times, yes, like WW2. We will do it, because there really is no choice to do otherwise. Our individual situations vary. Everyone has troubles right now. So everything we do will require extra kindness. Draw upon the compassion reservoir.

Reach deep. The capacity you need right now, is there.
