driven on by some demon

“Writing a book is a horrible, exhausting struggle, like a long bout with 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.”
― George Orwell

“The essence of being human is that one does not seek perfection.”
― George Orwell, In Front of Your Nose: 1945-1950

“Being in a minority, even in a minority of one, did not make you mad. There was truth and there was untruth, and if you clung to the truth even against the whole world, you were not mad.”
― George Orwell, 1984
