Chapter 3 · Part 2
Writing and editing
Writing is what ChatGPT is best at, and where most people use it worst — by asking it to write the whole thing from scratch and pasting the bland result. The trick is to use it as a drafting partner and editor, not a ghostwriter. You stay in charge of the ideas and the voice; it does the heavy lifting.
Get past the blank page
Its superpower is beating the blank page. Dump your rough thoughts and let it organize them — you'll get something to react to, which is far easier than starting cold:
Here are my messy notes for a resignation letter. Turn them into a warm,
professional two-paragraph letter. Keep it gracious — I liked the job.
Notes: leaving in 3 weeks, taking a role closer to family, grateful for the
mentorship from Dana, happy to help train a replacement.Use it as an editor
Often the best move isn't "write this" but "improve this." Paste your own draft and ask for a specific kind of edit — that keeps your voice while fixing real problems:
Tighten this to half the length without losing the main point.
Flag any sentence that's unclear.
Keep my casual tone — don't make it sound corporate.
[paste your draft]Instead of one rewrite, ask for three versions in different tones — "one warmer, one more direct, one more formal." Choosing between options is faster than critiquing a single draft, and you often end up mixing the best bits.
Teach it your voice
Left alone, ChatGPT writes in a recognizable, slightly generic style. To sound like you, give it a sample of your actual writing and tell it to match:
Write a reply to this customer using the voice in the sample below —
short sentences, friendly, a little playful, no jargon.
Sample of my writing: [paste 2-3 of your real messages]
Customer's message: [paste it]Iterate — don't accept the first try
The first answer is a starting point, not the final one. Steer it with plain follow-ups in the same chat: "more concise," "less salesy," "add a line about the deadline," "that intro is weak, try three others." Conversation is the tool.
The best AI-assisted writing still sounds like a person because a person shaped it. Read every word before you send it, cut anything that isn't true or isn't you, and never publish something you haven't actually checked. The context habits from Chapter 2 apply to every prompt here.
