" I don't know anything but the simplest rules of English grammar, and I seldom consciously apply them. Nevertheless, I instinctively write correctly and, I like to think, in an interesting fashion. I know when something sounds right and when it doesn't, and I can tell the difference without hesitation, even when writing at breakneck speed. How do I do this? I haven't the faintest idea. "

― Isaac Asimov
