There was a time when I kept far too much information in my head.

Appointments. Client meetings. Things the kids needed. Medical appointments. Calls I had to make. Business deadlines. Family commitments. Things for the house. Appointments for the dogs.

And, of course, the constant internal reminders:

Don’t forget to call them.

Remember that appointment.

You need to book that.

What time was that meeting again?

None of those things individually seemed overwhelming. But together, they were taking up mental space.

That is one of the challenges with mental load. It is not always one big responsibility creating the pressure. Sometimes it is the dozens of small things your brain is continually trying to remember, organize, anticipate, and keep moving.

One of the systems that has made a significant difference for me is something incredibly simple:

My calendar.

But I don't simply put appointments into it.

Over the years, I have turned my calendar into a system that allows me to move information out of my head and into a place I trust.

I Started Colour-Coding My Life

I began colour-coding my calendar about six or seven years ago.

I had seen other people doing it before, and initially, I didn't think it would make much difference.

It did.

I created different colours for different areas of my life.

Personal commitments have a colour. Medical appointments have a colour. My children have their own colours. My husband has one. The dogs have one. Household responsibilities have their place.

My business has its own colour categories as well.

For example, Carolyn Dickinson International is green on my calendar. If I am working closely with a particular client over an extended period, that client may have their own colour.

At a glance, I can look at my day or my week and immediately understand what I am walking into.

Is this predominantly a business day?

Do I have personal responsibilities mixed throughout it?

Are there several family appointments?

Is my schedule becoming too full?

I don't have to read every calendar entry to understand the bigger picture.

The colours show me.

And something that started as an organizational tool gradually became much more important.

It became a way of reducing what my brain had to hold.

I Don't Need to Keep Reminding Myself Anymore

Before I developed this system, I could put an appointment into my calendar and still mentally carry it.

I would think:

I have that appointment tomorrow.

Don't forget the meeting at 2:00.

Remember to make that call.

Technically, the information was already written down, but mentally I hadn't released responsibility for remembering it.

That is what changed.

Once I built a calendar system I trusted—and started using reminders consistently—I became much more comfortable allowing the calendar to hold that information for me.

That may sound small.

It isn't.

Every responsibility you can safely move out of your working memory gives your brain one less thing to continually rehearse.

I still have plenty going through my mind. Like most professional women, there are periods when there is a great deal happening professionally and personally.

The difference is that I don't need to carry every date, time, appointment, reminder, and task in my head at the same time.

My Calendar Doesn't Just Tell Me Where I Need to Be

I also use my calendar to create space for the things I need to accomplish.

At the end of the day, or first thing in the morning, I look at what is coming over the next few days.

Then I ask myself:

What actually needs to happen tomorrow?

There are often several small administrative things that need attention—booking a doctor's appointment, calling the veterinarian, following up with someone, confirming something for the family, or dealing with a quick business matter.

Instead of allowing those items to float around in my head all day, I group them.

I might block 30 minutes between 9:00 and 9:30 and list several calls or appointments I need to make.

Most of the time, I can complete them quickly.

Sometimes I simply leave a message and make a note of when I am available for the return call.

Either way, I have taken action.

And once I have dealt with it, I don't need to keep thinking:

I still need to call them.

That mental tab can close.

I Also Block Time for My Most Important Work

For my business, I usually identify the top three things that need my attention that day.

Then I give them actual space in my calendar.

If something will probably take an hour, I book the hour.

If I expect something to take 30 minutes, I may give myself 45.

Because we all know how often a “quick task” turns into something slightly bigger.

I purposely leave some breathing room.

The goal is not to create a schedule where every minute of my life is controlled.

In fact, that can create another form of pressure.

The goal is to create enough structure that I am not spending my day repeatedly asking myself:

What should I be doing right now?

That question creates more mental load than we sometimes realize.

When I already know what requires my attention, I can focus on doing the work instead of constantly deciding what to do next.

Sometimes the Fastest Solution Is Not Another Email

I also look at how I am using my time to solve problems.

There are situations where a 15-minute conversation can resolve something that might otherwise require 20 emails going back and forth.

So when appropriate, I make the call.

For me, reducing mental load is not just about remembering fewer things.

It is also about reducing unnecessary friction.

How can I make this simpler?

How can I make the decision faster?

Can this be handled now instead of allowing it to sit in the back of my mind for the next three days?

Not every issue can be solved immediately.

But when something can be closed, clarified, scheduled, or delegated, I try not to leave that mental tab open unnecessarily.

And Yes, Even With a System, I Have Forgotten Things

I want to be very clear about something.

Having a system does not mean I execute it perfectly every day.

There have been days when something was properly entered into my calendar.

The reminder appeared.

And I still forgot.

Usually it has been because something completely unexpected happened—an emergency or situation that suddenly required all of my attention.

It is rare for me, but it happens.

And when it does, I don't believe the answer is to beat yourself up because your system somehow “failed.”

Life happened.

You address what happened, find the best solution you can, correct the situation, and move forward.

The purpose of a system is not perfection.

The purpose is to reduce how often things fall through the cracks and reduce how much information you have to mentally carry every day.

That distinction matters.

I Book Things While They Are in Front of Me

Another habit that has reduced my mental load is very simple.

If I am with someone and we decide we need to meet again, I pull out my phone.

We look at our calendars.

We choose the date.

I book it.

Done.

I don't tell myself:

I'll check when I get back to the office.

Because that creates another responsibility I now have to remember.

My phone and computer are synchronized, so anything added to one immediately appears on the other.

The system travels with me.

Once something is booked, I don't have to continue carrying the question of when it will happen.

Your Calendar Can Be More Than a Place for Appointments

This is one of several methods I use to manage my own mental load, but it is probably the system I interact with most consistently.

And I think that is why it works.

A useful system should not make your life more complicated.

It should make something easier.

For me, my calendar gives me visibility.

It gives me structure.

It reduces the number of things I need to remember.

It allows me to see when my days are becoming too full.

And it gives me somewhere reliable to put responsibilities instead of asking my brain to keep holding onto them.

If you are carrying a lot right now, you may not need an entirely new productivity system.

Start smaller.

Look at what you are repeatedly trying to remember every day.

The appointments.

The calls.

The follow-ups.

The family responsibilities.

The work deadlines.

The tiny things that keep popping back into your thoughts because your brain is afraid you might forget them.

Then ask yourself:

Does all of this really need to live in my head?

For me, the answer was no.

My calendar became one place I could put some of that load down.

And that has made a bigger difference than I ever expected.
