Like aspiring actors who, for obvious reasons, move to LA, a number of aspiring writers move or desire to move to NYC to be near other writers and (potential) agents and publishers, but, per Nebraska born novelist Willa Cather, storehouses of literary material can be found anywhere - even in Nebraska or a pigpen. Cather reportedly advised:
Of course Nebraska is a storehouse of literary material. Everywhere is a storehouse of literary material. If a true #artist were born in a pigpen and raised in a sty, he would still find plenty of inspiration for his work. The only need is the eye to see.
However, it must be noted that Cather moved to NYC at the age of 33 and lived here until she died at the age of 73.
