Quotation of the Week: Willa Cather
“Most of the basic material a writer works with is acquired before the age of fifteen.”
–Willa Cather, d. 4/24/47
Not sure exactly which source to cite to this one, but I found it on Twitter via the reliable @katcop13.
It looks like the quote comes from a profile of Cather in the journal The Bookman from 1921.
