mAIn Street #144: Harvard study on AI use in white-collar work; Prompts to Improve Pricing Strategies Reverse Engineer Anything


DECEMBER 18, 2025

I don't know about the rest of you, but these last few weeks have seemed to go both super-fast and agonizingly slow.

I've barely Christmas-shopped. Workload never seems to decrease. I'm running out of time in one area and have more than I want in the other.

But next week starts two glorious weeks off, including Christmas, and I'll probably be keeping a low profile unless there are some major announcements. That said, we've got two more to go until the end of the week, so let's not dillydally. Here's what I've got for ya:

Prompts to Improve Pricing Strategies, Reverse Engineer for Better Results, and Audit the Quality of Your Relationships

  • SaaS pricing strategist prompt for tiered plans: System prompt that turns ChatGPT into a pricing strategist to generate Basic, Pro, and Enterprise tiers, each with differentiating features and suggested price points, output as a comparative Markdown table for new SaaS offers. (Reddit)
  • Reverse prompt engineering method to refine prompts: Shows how to paste in a finished example, ask the model to infer the hidden structure, and get back a reusable “reverse-engineered” prompt that recreates that tone, pacing, and formatting instead of guessing from scratch. (Reddit)
  • Simple conversational tricks that boost AI reasoning: Shares tiny phrasing tweaks like “Let’s think about this differently” and “What am I not seeing here?” that reliably surface blind spots, deeper structure, and context you forgot to mention—plus a link to a broader prompt library. (Reddit)
  • Year-end relationship audit prompt for honest review: A “relationship strategist” prompt that walks you through evaluating which relationships energize or drain you, analyzing patterns, setting boundaries, and planning where to invest time—designed as a PromptFuel lesson with copy-paste instructions.

DECEMBER 30, 2025 I hope you all had as wonderful a holiday as I did. Among the goodies I picked up from loved ones were the Meta RayBan Wayfarer Gen 2 Smartglasses.

I also got my butt handed to me in multiple games of Mario Kart World on the Switch 2. That I don't see changing any time soon. Anyhow, it's refreshing to be back on schedule. We have a LOT of...
