We all know of people who would come to work sick, whether they are taking something to relieve the symptoms or not. They wander around the work place in a fever-induced delirium with their sniffling noses and hacking coughs. It's the least you can do. But when books are opened, you discover that you have wings. Good writers are born, not made.
Good writers work alone.
Good writers know what they are going to say before they start writing. All good writers make complete plans and outlines before they write. They continue to plan as they compose, reorganizing, changing, and adding material as they write and revise. Good writers get it right the first time. Good writing comes from knowing all the rules of grammar.
