If Your Team Still Needs You, You Haven't Built a System

Most leaders automate the busywork but keep the authority. That's not efficiency - it's just documented dependency. Here's what actually works.

Stop Accepting Lunch Meetings - Your Calendar Isn't a Democracy

I reject every lunch meeting invite now. Not because I'm difficult, but because back-to-back meetings without food and a mental reset is a recipe for burnout. Here's why this boundary matters.

Why Are We Really Chasing Success?

We say we work hard to spend more time with our families. But what if the "work" is exactly what’s causing us to miss the very moments we’re working for?

What My Daughter's "No" Taught Me About Boundaries

Toddlers don't negotiate their boundaries. They just have them. Here's what that's teaching me about the difference between a decision and a pitch for permission.

The Most Fragile Job Security Is Being Irreplaceable

I've been made redundant twice, and it's the reason I now try to make myself redundant on purpose in every role I take. Not by disappearing. By building systems so the work runs without me as the bottleneck, then moving on to a bigger problem. Most people chase the opposite. They hoard knowledge, guard the process, and call being irreplaceable "job security." It's the most fragile position you can be in. Here's what making yourself dispensable actually looks like, and the Week 1 version you can start on Monday.

The Room Doesn't Resolve It Anymore

Half-day workshops with 45 people used to need to accomplish everything in the room. They don't anymore - and that changes how you should design them. This post makes the case for a new division of labour: the room surfaces contested decisions, social accountability, and tacit knowledge that AI can't manufacture. AI handles the sequencing logic, dependency modelling, and delivery planning that used to consume the best hours of the day. But the handoff only works if you design the session - before anyone walks in - to produce artefacts AI can reason over, not just summarise.

The Barista I Barely Know Told Me I Was Aging Fast - That's When I Knew I'd Lost Control

When someone you see twice a week but never really talk to stops you to say you're aging rapidly, you've crossed a line you can't ignore anymore.

I Built an AI That Thinks Like Me. Here's the Gap I Had to Architect For

Most AI assistants regurgitate content. This one reasons through problems the way I do. The four-node pipeline that makes intelligent mimicry possible.

The Gap Between Where You Are and Where You Want to Be Isn't as Large as You Think

I stopped waiting for 'someday' the moment I realised my daughter was watching. Here's what I'm teaching her about living now instead of deferring everything to a future that may never come.

I'm Not Using AI To Work Faster. I'm Using It To Be In Five Places At Once.

Most people are chasing speed. I'm building something different - an agentic version of myself that runs my frameworks, thinks the way I think, and just told me what it wants to learn next. That's when I knew this wasn't a tool anymore.

The Parent Window Is Shorter Than You Think

I'm someone who is always building toward something. But the thing nobody prepares you for when you become a parent is the daily tension between the person you're trying to become and the parent you need to be right now."

You're Not Building an AI Advantage. You're Building Someone Else's.

The platform is a commodity; your data is the fuel. Stop renting an AI advantage and start building a moat. If your data trains a general model, you're just funding a competitor’s future.

The Developer Built It While I Was Still Reading The Approval Docs

Before you automate a process with AI, ask if the process should exist at all. Most organizations are just making their bloat faster and more expensive.

I've Been Watching Businesses Become Zombie Corporations. Here's How to Tell If Yours Is Next.

Stop building "Zombie Corps." Automation looks elite on paper until you've hollowed out the human judgment that catches churn before it hits the P&L. If you can't explain the "why," you're just dying.

My Sunday Self Would Be Embarrassed Watching My Monday Self Work

I added three tasks to my backlog yesterday while making coffee. Hands-free. Voice command. Done before the kettle boiled. At work, I spent 15 minutes manually creating one Jira ticket.

AI Made Us More Productive, So Why Are We Drowning in Reports?

We automated the work. Then we automated the reporting. Then we automated the analysis. Now someone has to read all of it. This is the efficiency trap nobody's talking about.
