The secret to writing rapidly and well is not to self-edit. And the secret to avoiding self-editing is to stop trying to please the reader and be liked. Simply write the truth. Writers should make people think, not try to elicit support and/or pander to popularity. If you’re an expert, write like one. If you’re not an expert, then become one before you write. Simply writing a book doesn’t make you an expert any more than reading one automatically makes you educated.
