On writing characters…
“It does not matter whether your intent is to portray someone real or someone heroic. To make either type matter to your readers, you need only find in your real human being what is strong, and in your strong human being what is real . . . How do you find the strong or human qualities in your protagonist? What will be most effective to portray? The answer to those lies in you, the author. What is forgivably human to you? What stirs your respect? That is where to start.”
