"Why do you write? I write because I have an innate need to write! I write because I can't do normal work like other people. I write because I want to read books like the ones I write. I write because I am angry at all of you, angry at everyone. I write because I love sitting in a room all day writing. I write because I can only partake in real life by changing it. I write because I want others, all of us, the whole world, to know what sort of life we lived, and continue to live, in Istanbul, in Turkey. I write because I love the smell of paper, pen, and ink. I write because I believe in literature, in the art of the novel, more than I believe in anything else. I write because it is a habit, a passion. I write because I am afraid of being forgotten. I write because I like the glory and interest that writing brings. I write to be alone. Perhaps I write because I hope to understand why I am so very, very angry at all of you, so very, very angry at everyone. I write because I like to be read. I write because once I have begun a novel, an essay, a page, I want to finish it. I write because everyone expects me to write. I write because I have a childish belief in the immortality of libraries, and in the way my books sit on the shelf. I write because it is exciting to turn all of life's beauties and riches into words. I write not to tell a story, but to compose a story. I write because I wish to escape from the foreboding that there is a place I must go but—just as in a dream—I can't quite get there. I write because I have never managed to be happy. I write to be happy."
Why do I write? Because I can't help myself. I'm impelled to write. Sometimes I wish I could just be a simple baker or salesman or burger flipper but, alas, I am impelled to write.
