Who’s right?

So… I stumbled onto these two quotes within a few seconds of one another…

“In order to write about life, first you must live it!”

– Ernest Hemingway (1899 – 1961), writer, journalist

But then:

“A writer doesn’t need to go out and live, but stay home and invent.”

– Ned Rorem, Pulitzer Prize-Winning American Composer

Which is it?

Come on. Time’s wasting, and I need to know.
