In early 2023, after teaching 6,000 students over six years, I abruptly decided to stop teaching our Building a Second Brain cohorts. Even at that early stage, with the release of the first version of ChatGPT just a couple months earlier, it was clear to me the impact this new technology would have. Almost from…
A new, powerful definition of intelligence is emerging out of the AI field: “boundary intelligence.” I first came across it in this excellent piece To Know Is To Stage by Venkatesh Rao, which appropriately, was co-authored by an LLM. Let me step back and explain what boundary intelligence means (mixing my own words with paraphrasing…
I’m proud to introduce Death Clock, a life expectancy calculator that predicts the day of your death based on 17 personalized variables. Give it a try for free! This is not only the first “app” I’ve ever created myself, but also my first experience with AI-assisted coding, which has become known as “vibecoding.” I can…
At the end of each year, I sit down to reflect on my milestones and memories—big and small—that shaped the past 12 months. It’s become one of my favorite rituals to celebrate progress and set the stage for what’s next. Thankfully, technology can do a lot of the heavy lifting, making this process easier and…
About six months ago, I decided to evaluate a few of the newer generation of Second Brain apps. I’ve been using Evernote for 10 years and wanted to see if any of the up-and-comers could take over as my platform of choice. I tested three of the most promising ones – Obsidian, Tana, and Mem

I’ve had some form of a Second Brain (a personal system of knowledge management) for a couple of decades now, and during that time it’s been hosted on four different platforms. Recently, I sat down to reflect on what made me switch from one platform to the next and why I haven’t moved yet to
Two books I read recently helped me tremendously to understand what’s happening now with Artificial Intelligence: Prediction Machines and Power and Prediction (affiliate links) by Ajay Agrawal, Joshua Gans, and Avi Goldfarb. The authors are economists and professors at the University of Toronto, one of the leading institutions studying the economic impacts of AI. Their…
Imagine for a moment the perfect organizational system. A system that told you exactly where to put every piece of information in your life – every document, file, note, agenda, outline, and bit of research – and exactly where to find it when you needed it.
I sat down with productivity YouTuber Francesco D’Alessio of Keep Productive in London to rank our biggest productivity app predictions and share how we currently perceive the software space. Here’s a sneak peek of what we discussed: Is Mem the new Evernote? Will Notion lose in the next 3 years? Is Evernote going to make a comeback?…
We’re supposed to hate email and everything it represents. But I have a confession to make. I love email. (Scandalous, I know.) When it comes to email, I always think about the alternative: What would I do if there was no email at all? Write letters? Telegrams? Or most terrifying of all… get on the phone…
I recently joined Vishen Lakhiani, Founder and CEO of the education company Mindvalley, on the Mindvalley Podcast to talk about the 4 essential tools I think every modern professional needs in their toolkit. I also talked through my CODE methodology, which lies at the heart of my approach to building a “Second Brain.” Listen below, or visit…
