' Writers are the torchbearers of civilization. We're set in a corner only we
can illuminate.Some of us are searchlights, able to cast a beam into the 
far reaches of the human soul.Some of us are candles , barely able to 
sustain a glow against the darkness. Nevertheless the words I write 
are important, because light is additive. Another's light  doesn't diminish
 my own. Our lights together make us stronger.'   
                   - (After much paraphrasing and reaaranging) Roger Martin
