To a reader, substance is paramount, but not to a writer. A writer takes what is in the imagination and puts what’s there into words. Imagine taking up a pencil and drawing what is there before you. Unless you are a master, what you draw will not accurately capture what you see. Words and thoughts are similar in this regard. Only with constant emphasis on clarity can ideas gain the necessary strength to leap across time and space.

If I don’t think it’s good enough, it isn’t. Writing is as much contemplation as putting words to paper, and that takes time. Without that, there is no genius; and without genius, it’s simply not good enough. Genius, like a light, will shine through eventually, but it is my lot as a writer to always strive in that direction, even if the timing of that recognition is outside my control.
