Incredibly hard to understand. As if, say, Einstein waved his hand and produced a rigorous theory of the general relativity. And spent no time on it himself. Or if, say, Coltrane revolutionized music but never practiced.

I agree that adversarial interactions can produce results. That's not what the OP is saying. What the OP is saying is that you need a whole lot of self understanding to create good work in the space of writing.
