“Over and over again I have started writing about something really interesting or useful—classical stuff, matters of public interest, the Lord knows what—only to be pulled up with a jerk. Just as I am getting absorbed in it, up comes Burden. ‘Hi!’ he says. ‘I want you! You must stop that!’ I stop with a wrench and an abiding grudge against him. And when five or six weeks later there is a chance to start again, I shrink from re-absorption—remembering the wrench. You can’t really write with any force about anything on which you are never allowed to fix your attention.”
