Common first-draft mistakes include: including too many details in stories, using parentheses unnecessarily, having paragraphs of the same length, and making bone-headed spelling errors.
When writing stories, it is important to strike a balance with the number of details, killing unnecessary parts to keep the story powerful and focused.
Avoid using parentheses excessively, as often their content can be removed without affecting the message.
Vary the length of paragraphs to avoid a monotonous wall of text, adjusting them to maintain reader engagement.
