Not Everything Deserves a Slot

Yesterday I wrote about cognitive load theory. The science that says your brain has about 7 working slots, and most people are filling them with noise before they even sit down to do real work.

This week I want to go deeper on the personal side before we get to the work and AI applications. Because I think the hardest thing for any leader is focus. And focus is really just cognitive load management with a different name.

Focus is the hardest skill nobody teaches.

I have been working on focus for the last year and change. Not in a "buy a productivity planner" way. In a "rebuild how I allocate my brain" way.

Here is what I learned: focus is not about willpower. It is about what you remove. Every slot you clear by removing noise is a slot that becomes available for real work. You do not get more focused by trying harder. You get more focused by having fewer things competing for your attention.

That is why deleting Instagram mattered. It was not about the time I saved. It was about the slots I reclaimed. Every time I picked up my phone and scrolled for 10 minutes, my brain did not just lose 10 minutes. It lost cognitive slots to attentional residue that lingered for the next hour.

ADHD brain, 20 slots, nothing finished.

I describe myself as having ADHD energy. I do not know if that is a clinical diagnosis or just how I am wired, but here is what it looks like: I can have 20 things going at once. I love starting things. I love the rush of a new idea, a new project, a new initiative.

But 20 slots means nothing gets finished. You spread yourself so thin across so many things that none of them get the depth they need. You are technically busy all the time and making real progress on nothing.

The science explains this perfectly. Each of those 20 things is eating a slot. Even when you are not actively working on something, if it is on your mental to-do list, it is taking up space. Your brain is holding it. Tracking it. Worrying about it in the background.

The science: Zeigarnik Effect (1927): incomplete tasks occupy working memory more than completed tasks. The brain continues to process unfinished goals, creating a persistent cognitive load even when attention is directed elsewhere. This effect is amplified when there are many concurrent unfinished tasks, as each one generates its own attentional pull on working memory resources.

In plain English: Unfinished projects haunt your brain. Every open loop, every half-done initiative, every "I will get to that eventually" item is quietly eating a slot in the background. Twenty open projects is not ambition. It is twenty tiny weights pulling at your working memory all day long. Your brain will not let go of them until they are done or deliberately closed.

Once I understood this, I stopped wearing "busy" as a badge. Twenty slots going at once is not a flex. It is a sign that you have not decided what actually matters.

The four things that earn a slot.

I said this last week, but I want to expand on it because I think it is the most practical framework I have ever built for myself.

Family. Career. Health. Outdoor recreation.

That is my filter. When something new shows up, whether it is an opportunity, a request, a relationship, a piece of content, a distraction, I run it through the filter. Does this serve one of these four things? If yes, it gets a slot. If no, it does not.

This sounds simple. It is brutally hard to execute. Because the world is designed to convince you that everything is important. That you should care about everything. That you are missing out if you do not have an opinion on every topic, a presence on every platform, a finger in every pot.

You are not missing out. You are protecting the only resource that actually matters: your cognitive capacity.

Removing people is the hardest cognitive load decision.

I mentioned last week that I have started removing people from my life who are cognitive load drains. I want to be more specific about what that means because I think a lot of people need to hear it.

There are people who, every time you interact with them, leave you heavier. They bring problems but never solutions. They bring drama but never resolution. They vent but never act. Every interaction fills your slots with their noise.

I have done this instinctively most of my life. I have always kept a small circle. But now I understand the science behind why it works. Those people are not bad people. They are just consuming a resource I cannot afford to give away. My working memory.

Removing does not have to mean a dramatic confrontation. Sometimes it is just less. Less time. Less availability. Less engagement with the drama cycle. The slot opens up quietly, and you fill it with something that serves your four priorities.

This is not about being a robot.

I want to be clear. I still watch TV. I still have lazy mornings. I still have conversations that go nowhere productive. I am human.

But the difference between now and two years ago is awareness. I notice when I am spending slots on noise. And I make a choice. Sometimes the choice is: I need this downtime, and that is fine. But it is a choice, not a default.

Most people have never audited their cognitive inputs. They absorb whatever is in front of them. They scroll because the phone is there. They watch because the TV is on. They engage because someone texted. No filter. No intentionality. And then they wonder why they cannot focus.

Focus is not something you find. It is something you create. By removing everything that does not earn a slot.

If you are reading this and thinking "I cannot do any of that" -- start here.

I know some of you are running companies where the board expects you in every meeting. Where your co-founder needs you on every decision. Where the org chart says you own 15 things and you cannot just hand 10 of them to someone else.

I am not asking you to restructure your life this week. I am asking you to reclaim one slot.

One. That is it. Find the one recurring commitment that produces the least value for the most cognitive cost. The weekly meeting that could be biweekly. The report nobody reads. The project you said yes to out of obligation. Close that one loop. Cancel that one thing. Say no to that one request.

When that slot opens, do not fill it with something else. Sit with it for a week. Notice what your brain does when it has one extra unit of space. I think you will be surprised by what shows up in that gap. An idea you have not had time for. A decision you have been avoiding. A conversation you have been putting off.

You do not need to delete Instagram and cut people out of your life to benefit from cognitive load theory. You just need to start taking your 7 slots seriously. One at a time.

Tomorrow, I am going to take this into the workplace. Because the same principles that work for your personal life, clearing noise, protecting slots, focusing on what matters, apply to how you structure your work and your team. And there are moves you can make right now that will change everything.
