If you ever feel insignificant...remember this from Neal A Maxwell (thanks Jamie!):
"The same God that placed that star in a precise orbit millennia before
it appeared over Bethlehem in celebration of the birth of the Babe has
given at least equal attention to placement of each of us in precise
human orbits so that we may, if we will, illuminate the landscape of our
individual lives, so that our light may not only lead others but warm
them as well."
