Let's put it this way: if you are a novelist, I think you start out with a 20 word idea, and you work at it and you wind up with a 200,000 word novel. We, picture-book people, or at least I, start out with 200,000 words and I reduce it to 20.
Kindness and a generous spirit go a long way. And a sense of humor. It's like medicine - very healing.
Fundamental preparation is always effective. Work on those parts of your game that are fundamentally weak.
