The 15-Hour Work Week is Here (If You Want It)

How to buy back 15 hours this week using AI

“Most entrepreneurs waste 80% of their time on tasks worth 20% of their value.”

That’s from Jodie Cook in Forbes this week. And when I read it, I didn’t argue. I just felt a bit sick. Because she’s right.

I know where my time goes. Sort of. I know the big things. But the small things? The fifteen minutes here, the twenty minutes there? The “quick” email that turned into an hour of back-and-forth? That’s where the time disappears. And it adds up to roughly 15 hours a week of work that doesn’t move the needle.

AI can give you those hours back. Not hypothetically. This week

.

The 80/20 time audit.

You think you know where your time goes. You probably don’t.

Most business owners have a rough mental model: “I spend most of my time on strategy and client work.” But when you actually track it, the picture is different. A huge chunk goes to admin. Scheduling. Invoice chasing. Formatting documents. Searching for files. Rewriting the same email for the fifth time this month.

None of that is growth work. All of it can be automated or drastically reduced with the right tools.

The first step isn’t buying a tool. It’s seeing the problem clearly.

Your first automation win.

Don’t try to automate everything at once. That’s how people burn out on AI before they even start.

Pick one thing. The single most repetitive, soul-crushing task in your week. The one where you think “why am I still doing this manually?”

Here are the usual candidates:

Email sorting and responses. If you answer the same types of emails every week, AI can draft responses for you. You review and send. What used to take an hour becomes ten minutes.

Scheduling. If you’re still going back and forth with “Does Tuesday work? What about 2pm?” just stop. Calendly, Cal.com, or even ChatGPT can handle scheduling entirely.

Invoicing. If you’re manually creating invoices, chasing payments, and reconciling accounts, tools like Xero with AI add-ons can automate 90% of that process.

Content repurposing. Wrote a blog post? AI can turn it into five LinkedIn posts, three email snippets, and a video script in minutes. Not great content, but a solid first draft you can refine.

Pick one. Automate it. Measure the time saved.

The admin energy drain.

This is the bit people miss. Admin doesn’t just cost you time. It costs you energy.

You sit down at 9am with the intention of doing strategic work. But first, you check email. Then you realise you need to chase an invoice. Then someone asks you to reschedule a meeting. Then you need to update a spreadsheet. By 11am, you’ve done nothing of value and you’re mentally exhausted.

Admin is a cognitive drain. It fragments your attention. It keeps you in reactive mode instead of creative mode. Even if you only save 30 minutes by automating your invoicing, the mental energy you get back is worth far more than 30 minutes.

Protect your recovered hours.

Here’s the trap. You automate 15 hours of admin. You feel great. Then you fill those 15 hours with more admin. Different admin, but still admin. And you’re right back where you started.

“AI gives you leverage without the overhead, drama, or management complexity.” But leverage is only useful if you point it at something worthwhile.

The recovered hours should go to growth work. Client conversations. Strategic thinking. Building relationships. Creating something new. The stuff that actually moves your business forward.

Block those hours in your calendar. Protect them like you’d protect a meeting with your biggest client. Because that’s exactly what they are.

The Practical Bit

For one day this week, keep a simple log. Every time you switch tasks, write down what you just did and how long it took. No fancy tool needed. A piece of paper works fine.

At the end of the day, mark each task as either “Growth” (talking to clients, strategy, creative work) or “Admin” (everything else).

Calculate the percentage.

Prepare for a shock.

PS: When I first did this exercise, my split was roughly 30% growth, 70% admin. I was spending most of my week on work that didn’t matter. Now it’s closer to 60/40 on a good week. AI didn’t fix that overnight. But it gave me the leverage to start shifting it. One boring task at a time.
