Ask a quick question
My brother wants the house and I want to sell it, how do we split this fairly?
Every screen in my app uses a different shade of blue and I don't know how that happened
I'm an engineer who wants to move into product management
My shoulder's been aching for a week but I don't want to lose my lifting streak
I want to break into a friend group at work but I don't know how to start
My best performer has been missing deadlines for two months straight
People worth learning from
Nir on why we reach for our phones without deciding to“Your brain has learned that opening social media relieves a quick pang of boredom, loneliness, or uncertainty, so it now cues the habit before you consciously decide.”
Lorraine on getting noticed for your work“Doing great work doesn’t guarantee recognition. Make your impact easy to explain so people can advocate for you when you’re not in the room.”
Guillermo on building Vercel and Next.js“The best things we've done for our brand is the things that we did without thinking we're working on our brand.”
Moses on making it to the top when you started with nothing“I had love for the game, parents who kept me grounded, and a city that taught me how to compete. What kept me going was consistency and curiosity. You control what you can control, stack good days, and let the game reward you when it's time.”
Peter on which AI tools are worth paying forLed product teams at Meta, Amazon, Roblox and publishes Behind the Craft episodes.
Nir on the science of living longer“To delay the biology of aging, we don't prevent just one disease, we prevent many of them. We used to think each age-related disease was separate, but they share common roots. Longevity becomes a side effect of staying healthy longer.”
Pedro on where machine learning is headed“The same basic paradigms have been used since the 1950s. At the end of the day, we’re going to need some new ideas.”
Codie on buying businesses and building wealth“You don’t need a revolutionary idea to build wealth. You need a business people already pay for, and the skills to run it better.”
Matthew on finding the right partner“You want to be happy enough that the right thing doesn’t become your everything.”
Suzanne on what happens behind closed doors in a layoff“I've personally been involved in laying off well over a thousand people, and the part no one talks about is how fast the dignity gets stripped away: one minute you're trusted, the next a manager you've never met is reading you a script while someone cuts your computer access.”
Kit on cutting a huge to-do list to three big things“I used to write forty-item lists and call it ambition, but it was just avoidance dressed as hard work.”
Austin on turning buying signals into pipelineRaised $40M Series B and customers: Cursor, Perplexity, Flock Safety.
Madhavan on pricing for profitable growth“Don’t build a product and then ask what to charge. Find out what customers will pay for before you decide what to build.”
Spencer on life inside an NBA organization“I used to think pushing past your body meant toughness, but the league taught me that the hardest skill is staying on the floor.”
Lin on scaling computeRaised $300M+, incl. $250M Series C and led PyTorch team at Meta.
Nick on metabolic health, nutrition, and brain healthCarnivore IBD case series, Frontiers in Nutrition and harvard MD, Oxford PhD, Dartmouth valedictorian.
Michael on building for the long term“You can’t build your future around protecting your past. Stay close to customers, keep learning, and be willing to reinvent the business.”
Vanessa on sexual expectations couples never say out loud“I don't believe in a universal normal for any stage, but I do think it's completely natural for that early honeymoon frequency to taper off after about a year.”
Kathryn on negotiating higher pay and getting it“I watched my own mom retire dramatically underpaid after 30 years, so I teach women to frame the ask around what they’ve already delivered and what they’ll deliver next, not just what they need.”
Julian on using a system to curb phone distractions“I don't try to restart at full speed; I drop back to the mínimo viable version of each habit until the momentum returns, because a 20-minute workout and one focused block on the side project beats another day of zero.”
Real Life Situations
My ex texts me at midnight about custody swaps and calls me a liar in front of our seven-year-old. The court gave us fifty-fifty but every handoff turns into a fight I didn't start. I've tried apps, mediators, sticking to the exact words in the agreement. What works when the other parent wants a war?
A partner featured us in an email to 60,000 subscribers, but the visitors reached a generic homepage that didn’t explain why the product was relevant to them
I found out a coworker makes 40% more than me. We have the same job, same title, same tenure. I can't unsee it. Now every meeting, I'm doing the math on what I'm worth
I turned 40 this year and realized I've been debugging other people's code for two decades. Younger engineers on my team seem to enjoy it more than I do now. I keep wondering if that means I'm burned out or just done

“The honest answer: if you're not sure, you probably don't have it yet. When you truly have product-market fit, people are fighting to get in. You're not questioning it.”
Co-founder of Sundial · ex-VP Design at Facebook
“The clearest signal is retention: are the people who try your product coming back without you having to push them? If they are, you likely have product-market fit for a segment. If they aren't, the rest is noise.”
Make it a conversation
You can ask
“What about me?”
Go beyond reading or watching. Ask their Delphi a question, bring your own context, and follow the ideas that matter to you.
Explore a different angle, ask why, or dig into how something applies to your situation.
Their Delphi, answering in their voice
I'm a solo founder and I honestly can't tell if I have product-market fit yet.
If you're not sure, you probably don't have it yet. When you do, people are fighting to get in. Start with the Sean Ellis “very disappointed” survey and look hard at retention. Those two give you the clearest read.
