I’m a self-confessed decluttering addict. I secretly worship Marie Kondo and thrive on minimalism, in all aspects of life. Yep, that’s me! But up until recently, my bouts of spring cleaning were solely focused on my physical environment…until I discovered that decluttering my mind was just as important as decluttering my space.

5 simple ways to declutter your mind

What is mental clutter?

Just like your home, your workspace, your pantry, your wardrobe or your shelves quickly (and sometimes “inexplicably”!) fill up with stuff, so does your mind. This phenomenon is referred to as mental overload: the state that occurs when the amount or intensity of information exceeds an individual’s processing capacity.

Mental clutter can include worrying about the future or ruminating about the past but what drains our brains the most is the huge amount of incomplete tasks that are floating around in our heads. Mark Atkinson, MD and human potential teacher, reports that the average number of incomplete tasks we have operating at any one time is between 20 and 50 when in actual fact, most people can only handle between 4-5 comfortably. 

How can it affect your life?

When your mind is cluttered, you lack focus. According to the Zeigarnik Effect (based on Psychologist Bluma Zeigarnik’s research), unresolved and interrupted tasks thieve the attention of your brain. The human mind hates unfinished tasks. Part of your energy is being swallowed up by each task and this can stifle your creativity. 

What’s more, according to science, if you’re unable to get through the backlog in your brain, you’ll be slower and less efficient in processing information which may lead to poor decision making. Having less mind space can also trigger bouts of anxiety and stress. And ultimately, that feeling of overwhelm leads to procrastinating: you’re trying to move in so many different directions at once that you end up getting very little done. If you’re often looking for ways to numb yourself (for example binge watching TV until late), in order to stop thinking, then you know how it feels.

Try these 5 steps to declutter your mind

The task may seem daunting at first…but the reward of experiencing the unlimited potential of a decluttered mind is worth the effort I believe!

Clean up

Don’t underestimate the freedom and creativity that come from decluttering and organising your living and working spaces. Your brain likes order, and constant visual reminders of disorganisation drain your cognitive resources, kill your productivity and reduce your ability to focus.

Go through your home, your workspace and your inbox and follow Marie Kondo’s wise guidance: “discard everything that does not “spark joy”. Donate and get rid of things you don’t use.” When the energy of your living or working space evokes clarity and organisation, then the life and work that unfold are inspired by that energy.

Brain Dump

This process can provide instant relief! Write on a piece of paper ALL of the outstanding tasks and things to be done: conversations with people, projects, personal life, finances, work life, etc. write them all down!

You can do this in one go or dedicate 10min each day to dump things on your list until you feel “empty”. Once you allow the floodgates to open, it’s incredible how much lighter you can feel and how much more clarity you can experience.   


Now, for some of you, the list you came up with in the step above may be rather huge! You need to categorise these items on your list in order of importance. “But everything is important!” I hear you say. Well, if that’s your perception, add the “urgent” category to your sorting. These are the tasks that will have serious negative consequences if you don’t address them in priority. Be very honest here. You can use the time management matrix inspired by Stephen Covey’s work HERE.

It pays to assess the important items on your list in line with your personal or professional values and your life goals. What items are most in line with them? Those should be your next priority, after your urgent items. Keep going until you’ve assigned a priority to each item on your list. 

Single Task

Multitasking may seem efficient on the surface, but studies have shown that multitasking actually reduces productivity and fills your mind with too much activity. Instead, go down your list of priorities and focus on one task at a time to avoid mental overload. To avoid getting lost in time, you can set a timer for how long you want to spend on any given task, to ensure you manage your time well. Clear away everything else, until you’re done with that task. Then focus on the next task, and so on.

Take action

When it comes to taking action, remember the three D’s: Decide, Delete and Delegate. 

  • Decide: whenever you have a task on your plate there are only two options: decide to do it now or decide to do it later. If you decide to do it later, schedule it now!
  • Delete: if you don’t have time and it’s not important? Be ruthless. Delete this task.
  • Delegate: what doesn’t need to be done by you? I know what you’re thinking…” No one can do this as well and as fast as I can!”. And even though it may be true to some extent, remember that the end goal here is to free up precious time to focus on what’s truly important to you. Asking for support is a sign of maturity and resourcefulness. 

As you go about the process of decluttering your mind, you’re freeing up energy and space to think clearly, focus on what really matters and reignite your passion and creativity. Your life will thank you for it.
