Is it the rule among people who write for publication never to proofread their own work Why?

It's absolutely not a rule that writers never proofread their own work! In fact, it's a crucial part of the writing process.

Here's why:

* Catching errors: Writers are the most familiar with their own work, and they can often spot errors that others might miss.

* Improving flow and clarity: By reading their work aloud, writers can identify awkward phrasing, repetition, and other issues that affect readability.

* Ensuring consistency: Writers can ensure that their writing style, tone, and voice are consistent throughout the piece.

The real reason for the misconception is that:

* Fresh eyes are essential: Even the most meticulous writer can become blind to their own errors after multiple reads. A fresh perspective from an editor or proofreader can catch mistakes that were missed.

* Professional standards: For publication, especially in professional settings, an independent editor or proofreader is often required to ensure the highest quality of writing.

So, while writers are the first line of defense in catching errors, they don't avoid proofreading. They often engage in a multi-step process:

1. Self-editing: The writer proofreads and edits their own work multiple times.

2. Feedback: They share their work with others (beta readers, friends, critique partners) for feedback.

3. Professional editing: In many cases, they hire a professional editor to ensure their work is ready for publication.

In short, writers proofread their work, but they also know the value of fresh eyes and professional expertise.
