If a literary-minded witch gave me a choice that at a flick of her wand, I would either become an obscure novelist whose work will be admired and studied by a select few for decades, or a popular paperback author whose books give pleasure to millions. I would most likely choose to be a popular paperback author. At least, people will understand the message I am trying to deliver in my books instead of searching over and over like some would search for non-existent treasure.
Of course, being someone whose work will be admired and studied for decades is good too but I rather have a lot of people read it than just a select few. Besides, I would not like my work to be treated like a lab rat.
