On Hemingway's writing routine

More than a half-century ago, George Plimpton interviewed Ernest Hemingway for the Paris Review and the entire interview is posted here. Plimpton starts with a discussion of his subject tracking his progress on an office wall: "The numbers on the chart showing the daily output of words differ from 450, 575, 462, 1250, back to 512, the higher figures on days Hemingway puts in extra work so he won’t feel guilty spending the following day fishing on the Gulf Stream."
