The full quote is from Churchill. 'The empires of the future are empires of the mind.'
To an aspiring fantasy writer creating empires of the mind is the goal. After all, isn't writing a matter of stringing words together in such a way that images, worlds even, are created in the mind of the reader?

Steven King, of whom I am not a fan, does say one thing that resonates. 'It's necessary to write a million words of b****x first before you can get to write the good stuff.' One reason to write a blog. Somehow or other you've got to write that one million words first, (some people say two million).
