(Outro bom site cheio de dicas e inspirações, o Brain Pickings. Nesse link, Samuel R.Delany definiu algumas diferenças entre Boa Escrita e a Escrita Talentosa)
Though they have things in common, good writing and talented writing are not the same.
[…]If you start with a confused, unclear, and badly written story, and apply the rules of good writing to it, you can probably turn it into a simple, logical, clearly written story. It will still not be a good one. The major fault of eighty-five to ninety-five percent of all fiction is that it is banal and dull.
Now old stories can always be told with new language. You can even add new characters to them; you can use them to dramatize new ideas. But eventually even the new language, characters, and ideas lose their ability to invigorate.
Either in content or in style, in subject matter or in rhetorical approach, fiction that is too much like other fiction is bad by definition. However paradoxical it sounds, good writing as a set of strictures (that is, when the writing is good and nothing more) produces most bad fiction. On one level or another, the realization of this is finally what turns most writers away from writing.
Talented writing is, however, something else. You need talent to write fiction.
Good writing is clear. Talented writing is energetic. Good writing avoids errors. Talented writing makes things happen in the reader’s mind — vividly, forcefully — that good writing, which stops with clarity and logic, doesn’t.
