Keeping your head in the light

Seems the challenge of life is to keep your own head in the light and
still look at the darkness (don't turn away and only look at the cheery side
of things). If you are really in the light, you will pierce the darkness with
your light and bring light to the dark.

Many religious groups teach people to only hang out with positive people.
I suppose they can only keep their positive attitude by being around others
who have a positive attitude. Perhaps their light is too dim or they don't
know how to restore it. It's sad, n'est ce pas? So unlike our great avatars.
