This reminds me of an observation I had when a family member, who had never talked about such things with me before, finally said he had an idea for a novel, and detailed it to me. He had never said anything about it before, he never said anything about it afterwards, and as far as I know, never worked on it.<p>Everyone has ideas for such in their heads, I think. Making up stories is a decidedly human activity. But what makes an author is not merely having an idea, but putting in the work to sit down, hammer out that idea, and refine it until it's good enough to sell. Even in the face of crippling self doubt, the knowledge people may not be interested, it may not find a publisher, etc, they're the ones who manage to get it done and get it out there.<p>I'd imagine correlations could be drawn to business ideas, but I don't know that business ideas are as universal as stories.
