I work in my sleep now. I fall asleep most nights writing and rewriting opening lines and first paragraphs in my head. And every morning before I wake, I am somehow still writing sentences in my head, twisted into my sheets while comparing arguments and searching for counter-arguments that could undo a whole story. This is probably not a good habit to be in, but taking work along to bed has become commonplace in the age of the self-funded permalance entrepreneur. A 2008 survey found 51 percent of small business employees saying they work in their sleep, and of those close to 70 percent try and apply the things they've dreamt about to their jobs the following day.
