72 minutes that might change how you use AI
Hi Reader, I recently did my first ever in-person interview. I sat down with Nathan Barry (founder of kit.com) and went deep for over an hour on AI. We called it The Ultimate AI Masterclass for Businesses in 2026, and honestly, that title earns its name. We get into the most important things you need to be doing right now to get the most out of AI:- context engineering, - workflow design, - the mistakes I see smart operators making every single day.- real examples, - and real systems you can...
I stopped re-explaining myself to AI
Hi Reader, Last week I posted something on LinkedIn about AI skills, and it went a little nuts. The response told me something: people are tired of re-explaining themselves to AI every single conversation. Same voice instructions. Same formatting preferences.Same "no, that's not what I meant" corrections.Same copy-pasting and heavy editing of everything. Every. Single. Time. That's the problem skill files solve. What's a Skill File? A skill file is a markdown document that teaches AI your...
AI gives you hours back. Then what?
Hi Reader, The hunger of our age isn't for more. It's for meaning. We have everything. And we're still starving. Two Kinds of Desire Some desires transform you.Some just distract you. Actually learning something hard rewires your brain.Scrolling leaves you exactly where you started. Both feel like satisfaction.Only one really is. This is the difference between deep desires and shallow ones. Deep desires change who you are. They require struggle. They leave you different than when you started....
I will die on the em dash hill
Hi Reader, A year ago, LinkedIn declared war on the em dash. For the record, I love the em dash. I will forever be waving the flag of the em dash. If there was an em dash brand, I'd buy all their stuff. I will never let it go. I will never give it up. Em dashes are the best. *ahem* Back to the war. Everyone said the em dash was an "AI tell." And it still is. But there's a bigger boogieman out to get you. The Real Pattern Look at these sentences: • "It's not about productivity. It's about...
I see this every week with AI teams (and it is't good)
Hi Reader, I see this every week. A company adopts AI. Everyone starts using it. Nobody's aligned. Marketing writes one way. Sales writes another. The founder writes a third. Same company. Three completely different voices. The Gap Nobody Talks About The biggest gap in AI adoption isn't tools. It's context. Everyone has ChatGPT. Or Claude. Or Gemini. But nobody has shared guidelines. No voice standards. No ICP definition. No operating principles. So every person gets a different AI—because...
15 months from 'last resort' to reality
Hi Reader, ChatGPT knows your questions, fears, and half-formed ideas. The career doubts you'd never say out loud. That weird rash you asked it about. The things you don't speak aloud. And now they're selling ads against it. The "Last Resort" That Took 15 Months Sam Altman, October 2024:"Ads are like a last resort for us as a business model." Sam Altman, January 2026:"We are starting to test ads in ChatGPT." X posts of Sam Altman in 2024 and 2025 talking about ads Fifteen months from "last...
I'm betting on Claude. Here's why.
Hi Reader, For years I said "use whatever AI works for you." ChatGPT, Claude, Gemini—pick one and go. This week, I stopped saying that. The Fork is Real The gap between AI tools is widening fast. Not in features. In actual business capabilities. Claude is shipping things that matter for real work: Claude Code (AI that actually writes and edits code) Claude Cowork (launched this week—Claude Code for non-coders) Computer use, file organization, data analysis ChatGPT is still a great personal...
Nobody noticed you were gone
Hi Reader,You come and go on social.You send a newsletter, then you don't.The world keeps spinning. The apology post is a trap.So is the "I know it's been a while since I sent one of these" email opener. Nobody was counting the days.They didn't notice. That sounds brutal.It's actually a gift. The Permission Slip You don't owe anyone an explanation. You don't need to start with "I know it's been a while..."You don't need to promise to be more consistent.You don't need permission to show up....
Everyone's building AI agents. Most are building the wrong thing
Hi Reader, Everyone’s talking about “AI agents” right now. But most people are confused about where automation stops and agents begin. Here’s the truth: they’re not as distinct as the charts make them seem. Automation: If this happens, do that. Boolean logic. Predefined rules. Fast, reliable, but rigid. AI automation: Same structure, but now you’re calling an LLM for one or more steps. Still deterministic overall, but with flexibility where you need it. AI agent: Non-deterministic. Adaptive....
Why your prompts fail — and the Meta Prompt that fixes it
Hi Reader, Save this (you’ll use it weekly). The right prompt is like magic. It gets you dependable results every time. It takes the frustration out of the creation process. It’s the foundation of a rock solid and repeatable workflow. But here’s the thing: A prompt needs to be custom to your task. So most copy-and-paste prompts aren’t valuable. Instead, you need to learn the Meta Prompt™. What it is: AI knows how to use AI better than people. Meta Prompting is using AI to create your prompt...
