How to Declutter Your Mind When You’re Carrying Too Much

There are days when my brain feels as though somebody has opened 37 tabs at once, one of them is playing music somewhere in the background, and I haven’t a clue which one it is.

You probably know the feeling. You’re making dinner while remembering an email you haven’t answered, wondering whether you handled a conversation badly, mentally adding toothpaste to the shopping list, thinking about something that needs to happen next Thursday and suddenly remembering you were supposed to book an appointment about three weeks ago.

Technically, nothing is on fire, but your brain would still like you to know that several potential fires are currently under review.

That’s the kind of mental clutter I’m talking about, and if you’re the person who tends to remember everything, organise everything and notice what needs doing before anyone else has even clocked that there’s a problem, there can be an awful lot of it.

We’re often told that the solution is to become more organised, find a better planner (one of my personal favourites!) or develop some sort of flawless morning routine, but sometimes the real answer is much simpler: you need less to organise in the first place.

Mental clutter isn’t just having too many things to do

When we talk about mental load, it’s easy to picture a long to-do list, but plenty of the things taking up space in your head will never appear on a list at all.

They’re the conversations you keep replaying, the decisions you haven’t made yet, the decisions you have made but keep reopening, the things you’re waiting for other people to do, the things other people should be remembering but somehow you’re remembering on their behalf, and the hours you can spend mentally preparing for reactions that haven’t even happened yet.

It’s not always the volume of work that leaves you exhausted; often, it’s the volume of unfinished business your brain is trying to keep track of at the same time.

That’s why you can sometimes get to the end of a day and think, I haven’t even done that much, so why am I wrecked?

Your brain, which has been running a small international logistics operation in the background since 7am, would probably disagree.

1.Start by getting it out of your head

When everything feels tangled, resist the urge to immediately create a colour-coded masterplan, because that can easily become another job in itself.

Instead, start by getting everything out of your head and onto paper.

Write down the obvious things such as work tasks, appointments, people you need to reply to and things you need to buy, but include the less tangible stuff too: the decision you’ve been avoiding, the conversation you’re still thinking about, the thing you’re annoyed about, the bit of life admin you’ve been meaning to sort since 2019.

Don’t worry about organising any of it at this stage, simply to stop asking your brain to hold everything at once.

Our brains are very good at spotting problems, making connections and generating elaborate scenarios about what might happen next, but they are fairly poor filing cabinets. Once you can actually see everything in front of you, rather than experiencing it as one big fog of stuff, the pressure often drops almost immediately.

2.Separate what needs action from what needs no more thinking

This is one of the most useful things you can do when your head feels full, because we often give worries the same status as actual tasks.

For example, ‘Email Sarah’ is a task.

‘What if Sarah thinks I’m being difficult?’ is not a task, although your brain may try to convince you otherwise.

‘Make a decision about the project’ requires action.

‘Imagine every possible way the decision might go wrong and rehearse your response to each one’ is your brain doing unpaid overtime.

When you notice one of these thoughts, ask yourself whether there is genuinely something useful you can do. If there is, decide what the action is and either do it or schedule it. If there isn’t, continuing to think about it probably won’t provide the certainty your brain is looking for.

This is particularly relevant if you’re prone to overthinking, because overthinking can feel incredibly productive while achieving very little. You can spend hours analysing something and still be exactly where you started, only considerably more tired.

3. Ask yourself what is actually yours to carry

This is one of my favourite questions, mainly because it is both incredibly useful and occasionally quite horrifying.

If you’re capable, conscientious and used to getting things done, you can end up carrying responsibility for all sorts of things simply because you noticed them first.

But noticing something and owning it are not the same thing.

Before automatically stepping in, ask yourself whether this is genuinely your responsibility. Not whether you could sort it, because you probably could. You could likely reorganise the household, rewrite the process at work and source a replacement plumber before lunchtime if required.

The more useful question is: who actually owns this?

Who needs to remember it? Who needs to make the decision? Who needs to deal with the consequence if it doesn’t happen?

This applies to mental load at home and at work. You can technically delegate a task while still keeping all the responsibility for remembering it, checking on it, reminding the other person and stepping in when they don’t do it exactly when you would.

That isn’t really delegating.

If someone else owns something, experiment with letting them own it. They may do it differently. They may even, steady yourself, do it later than you would.

Every time you take responsibility for something that belongs to somebody else, your brain gains another thing to monitor while theirs gains one less - funny how that works.

4. Stop reopening decisions and close the little loops

There is a particular kind of mental exhaustion that comes from making a decision and then refusing to let the decision stick.

You decide what you’re going to do, then reconsider it, ask someone else for their opinion, remember another detail, convince yourself you may have been too hasty and eventually drag the whole thing back into court for another hearing.

If no genuinely new information has appeared, allow the decision to stand - no need for further torment.

You don’t need complete certainty before moving forward. You need enough information to make a reasonable choice and enough self-trust to believe that you can deal with whatever happens next.

At the same time, deal with some of the tiny open loops that keep buzzing around in the background: the form that needs returning, the appointment that needs booking, the message you haven’t answered or the lightbulb you’ve remembered fourteen separate times and somehow still haven’t bought.

Sometimes your brain is repeatedly reminding you about something because you have repeatedly ignored it.

Fair enough, brain. Message received.

Give yourself 15 or 20 minutes to clear a few of the genuinely quick jobs, then give the remaining ones somewhere reliable to live - one calendar, one task list and one sensible place for notes will do nicely.

No one is handing out medals for administration.

5. Reduce what you’re pouring into your brain

It is very difficult to create mental space while continuously filling every available gap with more information.

Notifications, WhatsApp groups, emails, news alerts, social media, voice notes, podcasts and other people’s opinions all add to the noise. We consume an extraordinary amount of information and then wonder why our brains won’t switch off.

You don’t need to abandon modern life, move to a cottage in West Cork and throw your phone into the Atlantic, tempting though that may occasionally feel (though I’d highly recommend the West Cork cottage, in fairness!).

Start with some baby steps. Turn off notifications you don’t need. Leave the group chat you’ve been muting for two years. Try not to check your email every time your brain is looking for a quick distraction.

Most importantly, give yourself periods when nothing new is coming in, because your brain needs some room and time to process what is already there.

6. Remember that not every thought needs solving

Your brain produces thoughts all day long, and not all of them deserve a committee meeting.

What if she was annoyed with me?

Maybe she was.

What if I should have said something different?

Possibly.

What if this all goes horribly wrong?

A cheerful contribution, thanks a million!

You can notice a thought without immediately turning it into a problem that needs solving.

Sometimes recognising, ‘There’s my brain worrying about that again’, is enough.

You don’t have to argue with the thought, replace it with a positive affirmation or uncover its entire psychological history before lunch. Decide if it requires action, and if it doesn’t, practise letting it move along without giving it another twenty minutes of airtime.

That is part of self-trust too: learning that you don’t have to respond to every anxious thought as though it is urgent information.

7. Look at your boundaries, not just your to-do list

A cluttered mind is often connected to a life with too many commitments, too much availability, and too many people with very easy access to your time and attention.

Every yes comes with more than the task itself. There’s the planning, remembering, rearranging, thinking about it, possibly resenting it and then wondering whether you should have agreed in the first place.

A boundary can remove all of that at once.

Sometimes the simplest way to create more mental space is to say, “No, I can’t take that on.”

You may feel the urge to follow that with a lengthy explanation and several supporting documents, but you don’t always need to convince somebody that your boundary is reasonable.

The difficult part of boundaries is often not knowing what to say; it’s tolerating the feeling that comes afterwards when someone is disappointed, surprised or simply not delighted with your answer.

When you’re mentally overloaded, it’s easy to start blaming yourself. Why can’t I focus? Why am I so forgetful? Why is everything irritating me? Why can’t I just get more organised?

But if you are asking one brain to manage the workload, remember the appointments, anticipate problems, make decisions, monitor everyone else’s needs and somehow also remember what’s for dinner, perhaps your brain isn’t failing at all.

Perhaps it’s doing a fairly heroic job under the circumstances.

Decluttering your mind isn’t about becoming permanently calm or learning how to carry everything more efficiently. It’s about reducing what you’re unnecessarily carrying, allowing decisions to remain, holding better boundaries and letting other people take responsibility for what genuinely belongs to them.

You don’t need an empty mind, you just need enough space in it to hear yourself think.

If your head feels permanently full

This is exactly the kind of pattern I work on inside BLAZE Your Trail, because mental load is rarely solved by giving somebody another complicated system to maintain.

We look at what is actually taking up your capacity - the overthinking, second-guessing, responsibility and boundaries that keep you mentally switched on long after you want to switch off - and then work out what can change in your actual life.

Because sometimes the answer isn’t learning how to carry everything better.

It’s recognising what you can finally put down.

Blaze Your Trail. Not theirs. Yours.
