evidence: Ernest M. Hemingway "The writer's job is to tell the truth," Ernest Hemingway once said. When he was having difficulty writing he reminded himself of this, as he explained in his memoirs, A Moveable Feast. "I would stand and look out over the roofs of Paris and think, 'Do not worry. You have always written before and you will write now. All you have to do is write one true sentence. Write the truest sentence that you know.' So finally I would write one true sentence, and then go on from there. It was easy then because there was always one true sentence that I knew or had seen or had heard someone say."
