You Said It Saves Time. But You're Working on Sunday.

It’s Sunday morning. I’m about to leave for my favorite coffee place in Winterthur. My wife walks me to the door, looks at me, and says: “You said Copilot saves time. So why are you working on Sunday?”

I laughed. But she had a point.

I write about Copilot, talk about Copilot, build with Copilot, use it every single day. And every slide about generative AI promises the same thing: hours saved per week. It’s the headline number. It’s what executives want to see: the ROI on AI.

So why am I still working Sundays? Am I doing something wrong?

Does Copilot actually save time?

The honest answer, after years of daily use: my working hours haven’t dropped. I work roughly the same amount as before Copilot.

What changed is what I do during those hours.

Sunday is my routine day for writing. But what comes out during the week is completely different: deeper analysis, better client work, a weekly newsletter, courses, keynotes. Things that wouldn’t have been possible before.

So when someone asks “how much time does Copilot save you every week?”, my honest answer is: I actually don’t know. But the output I’m able to deliver is significantly higher.

AI didn’t give me more free time. It gave me capacity I didn’t have before.

Let’s not focus on how many hours you’ve saved, but on how much business impact you created. That’s a different value proposition. And I think it’s the more important one.

What changes with daily AI use: three practices

After years of daily use, three practices stand out. These are things I actually do — not theory.

More depth instead of more breadth. Before Copilot, my instinct was always to take on more. Projects, topics, meetings — the classic consulting trap: maximize the number of things you touch. Copilot inverted that. Because it handles the surface work — drafts, research, summaries, formatting — I can go deeper on fewer things. I haven’t saved a single minute. But within the hours I work for my customers, I produce higher quality.

Strategic thinking instead of doing. There’s a benefit of AI I can’t stress enough: it pulls you up the value chain. The hard part of a workshop isn’t drafting the slides. It’s how to structure the workshop and how to ensure the outcome you need. When Copilot handles the doing, there’s room for the question that actually matters. Not “how do I get this done faster?” but “should we even be doing this?” I have more time for client conversations about strategy and outcomes, more time to question my own assumptions before I commit to a direction. I don’t work less. But my cognitive ratio shifted.

Mental deload. This one is harder to explain, but I think it’s the most important. Before Copilot, complex tasks meant carrying everything in my head: the structure of the document, the open questions, what I researched yesterday, what was discussed in the last workshop. All of it at once, while trying to actually create something. Now I hand the structure to Copilot and let it guide me through: here’s where we are, here’s what’s next, here’s what’s missing. My head doesn’t have to hold the whole map. It just has to walk the next step.

One honest caveat: run too many things in parallel, and mental deload flips into mental overload. I’m still figuring out where that line is.

Why “time saved” is the wrong ROI question

Most leaders measure AI the wrong way. They ask their people: “How much time does Copilot save you?” Then they’re surprised when the answers are vague — and the CFO comes back with “well, at the end, costs are still the same.”

Here’s why that happens:

Time saved is invisible. Capacity gained is visible in the work.

Hours saved are invisible to the person living them. The minutes get absorbed into other work, and nobody can point to them on a calendar. What you can point to is the work itself.

The better question for decision-makers

There’s a better question: “What do you do differently with your time now?”

That answer is concrete. The sales rep who used to walk into meetings cold now arrives prepared with full client context — and the win rate goes up. The marketing team that used to spend Friday afternoons writing recap emails now uses that time to plan next week’s campaign. The analyst who used to format slides until midnight now ships a deeper analysis by early evening.

If you want to measure Copilot ROI, look at the work itself — and trust your people. Are the deliverables better? Are client conversations sharper? Do people spend their time on strategic work or on urgent firefighting? Those are the productivity metrics that actually matter.

And one more thing: this journey starts with personal productivity, but it’s a strategic investment at the same time. If your competitors use AI and you don’t, you’re at a disadvantage. If you use it and they don’t, you have an unfair advantage. At some point, others will follow. By then you’re already a step ahead — ready for the next layer, where AI moves from personal productivity into your business processes. That’s where personal productivity becomes organizational productivity.

What you do with the capacity is a choice

My wife was right and wrong at the same time. She was right about Sundays. Copilot didn’t save me Sundays. I’m still here, still writing, still putting in the hours.

But she was wrong about what success looks like. Time isn’t the only metric that matters. What Copilot gave me is a different kind of value: the capacity to do work I couldn’t do before, to think more clearly, and to carry less in my head while producing more on the page.

There’s a part of her observation I want to acknowledge, though. Just because AI lets you do more doesn’t mean you should fill every gap with more work. Personal productivity is also a personal choice.

Copilot is an amplifier. It amplifies whatever you point it at — including the tendency to overwork.

So the real question is what you decide to do with what it enables. For me, right now, that means writing on Sunday morning because I want to. And heading into the gym at six, because that’s the routine that gets me through the week — not because I have to.
