Writing According to George Orwell

"The problem of language is  subtler and would take too long to discuss. I will only say that of late years I have  tried to write less picturesquely and more exactly. In any case I find that by the time you have perfected any style of writing, you have always outgrown it. Animal Farm was the first book in which I tried, with full consciousness of what I was doing, to fuse political purpose and artistic purpose into one whole. I have not written a novel for seven years, but I hope to write another fairly soon. It is bound to be a failure, every book is a failure, but I do know with some clarity what kind of book I want to write. Looking back through the last page or two, I see that I have made it appear as though my motives in writing were wholly public-spirited. I don't want to leave that as the final impression. All writers are vain, selfish, and lazy, and at the very bottom of their motives there lies a mystery. Writing a book is a horrible, exhausting struggle, like a long bout of some painful illness. One would never undertake such a thing if one were not driven on by some demon whom one can neither resist nor understand. For all one knows that demon is simply the same instinct that makes a baby squall for attention. And yet it is also true that one can write nothing readable unless one constantly struggles to efface one's own personality. Good prose is like a windowpane. I cannot say with certainty which of my motives are the strongest, but I know which of them deserve to be followed. And looking back through my work, I see that it is invariably where I lacked a political purpose that I wrote lifeless books and was betrayed into purple passages, sentences without meaning, decorative adjectives and humbug generally."
