Monday Is Too Late to Plan Your Monday

Last Sunday evening, I did something that might sound mundane but has quietly become one of my most valuable weekly habits:

I pre-decided what I would wear for the entire week.

I stood in front of my wardrobe, looked at my schedule for the coming days, and intentionally selected Monday’s outfit, Tuesday’s outfit, Wednesday’s, and so on, right through to Friday.

It took maybe ten minutes.

And those ten minutes will save me mental energy every single morning this week.

The Hidden Cost of Small Decisions

Here’s something most of us don’t realise:

every decision you make, no matter how small, costs you something.

Psychologists call it “decision fatigue.” The idea is simple: your brain has a limited capacity for making decisions each day. Every choice you make, even tiny, seemingly insignificant ones, depletes that capacity.

Should I wear the blue shirt or the grey one?
Toast or cereal for breakfast?
Should I check email first or start with that report?
Do I respond to this message now or later?

None of these feel like big decisions. But by the time you’ve made fifty of them before 9 AM, you’ve already used up mental energy that could have gone toward more important choices.

This is why, by the end of the day, it’s so hard to make good decisions. You’re not lazy. You’re not undisciplined. You’re just depleted.

And here’s the kicker: the decisions that drain you the most aren’t the big, consequential ones. Those, you take seriously. You give them time and attention.

It’s the small, repetitive, low-stakes decisions that kill you.

What to wear. What to eat. When to do this task versus that one.

Death by a thousand tiny choices.

The Power of Pre-Deciding

So what if you could eliminate dozens of those small decisions before the week even starts?

What if, instead of standing in front of your wardrobe every morning trying to figure out what to wear, you already knew—because you decided on Sunday?

What if, instead of opening the fridge and wondering what’s for dinner, you already had a meal plan—because you decided on Sunday?

What if, instead of waking up and trying to figure out your priorities for the day, you already knew—because you mapped out your week on Sunday?

This is the power of pre-deciding.

You make the decision once, during a time when your mental energy is high and you can think clearly. Then, during the week, you simply execute what you’ve already decided.

No deliberation. No second-guessing. No decision fatigue.

Just action.

What I Pre-Decide (and When)

Here are some of the things I’ve started pre-deciding, and when I do it:

Sunday Evening: The Wardrobe

This is my newest habit, and I’m already seeing the benefit.

Every Sunday evening, I look at my week ahead:

• Do I have any meetings or events that require specific attire?
• Will I be in the office or working from home?
• What’s the weather forecast?

Then I select outfits for Monday through Friday. I don’t always lay them out (though some people do and sometimes I do), but I usually mentally lock in what I’ll wear.

Monday morning, I wake up, open the wardrobe, and grab what I’ve already decided. No standing there wondering. No trying on three different shirts. No decision.

Time saved: 3-7 minutes every morning.
Mental energy saved: Immeasurable.

Sunday Evening: The Week’s Priorities

I also use Sunday evening to review my to-do list and map out my week.

What are my top 3 priorities for the week? What needs to happen Monday? What can wait until Thursday?

I don’t schedule every minute. But I pre-decide where my focus will go each day.

This way, when Monday morning comes, I don’t waste the first hour of my day figuring out what to work on. I already know.

Monthly: Meals (In Progress)

I haven’t perfected this one yet, but my wife and I are working toward it.

The idea is simple: sit down once a month (or once a week) and decide what we’ll eat for the next several days. Not rigidly, we can adjust if something changes, but enough to eliminate the daily “What’s for dinner?” conversation.

Because here’s the truth: that conversation isn’t just about food. It’s a decision. And decisions drain energy.

If we pre-decide meals, we free up that energy for things that actually matter.

The Leaders Who Pre-Decide

I’m not the first person to discover this.

Some of the most successful, high-performing people in the world have built their lives around pre-deciding.

Barack Obama famously said:
“You’ll see I wear only grey or blue suits. I’m trying to pare down decisions. I don’t want to make decisions about what I’m eating or wearing. Because I have too many other decisions to make.”

Obama understood that leading a nation required thousands of high-stakes decisions. He couldn’t afford to waste mental energy on his wardrobe.

Steve Jobs wore the same thing almost every day: black turtleneck, jeans, New Balance trainers. Not because he lacked fashion sense, but because he’d pre-decided. One less thing to think about.

Mark Zuckerberg does the same. Grey t-shirt. Jeans. Done.

These aren’t people who can’t afford nice clothes or don’t care about their appearance. They’re people who understand that every small decision costs something, and they’d rather spend that currency on things that matter.

It’s Not About Laziness. It’s About Strategy.

Some people hear “pre-decide your wardrobe” and think it sounds rigid. Boring. Like you’re removing spontaneity from life.

But that’s not what this is about.

Pre-deciding isn’t about eliminating choice. It’s about eliminating unnecessary choice.

There are some decisions in life that deserve your full attention:

• How you’ll invest your time and talents
• What values you’ll instil in your children
• How you’ll respond to a difficult situation at work
• Which opportunities to pursue and which to decline

These are the decisions that shape your life. These deserve your best mental energy.

But what to wear on Tuesday? That doesn’t deserve the same level of thought. And yet, if you haven’t pre-decided, you’ll give it that thought anyway—simply because the decision is in front of you.

Pre-deciding is about protecting your mental energy for what actually matters.

How to Start Pre-Deciding

If this resonates with you and you want to try it, here’s how to start:

Step 1: Identify Your Repetitive Decisions

What small decisions do you make over and over, every day or every week?

Common examples:

• What to wear
• What to eat (breakfast, lunch, dinner)
• When to exercise
• What to work on first each morning
• When to check email or social media

Write them down. These are your candidates for pre-deciding.

Step 2: Pick One to Start With

Don’t try to pre-decide everything at once. That’s overwhelming.

Pick one repetitive decision and pre-decide it for a week.

I’d recommend starting with your wardrobe, it’s simple, low-risk, and you’ll feel the benefit immediately.

Step 3: Create a Pre-Deciding Ritual

For me, it’s Sunday evening. After church, after rest, before the week begins.

I sit down, look at the week ahead, and make decisions:

• What will I wear?
• What are my top priorities?
• What needs to happen when?

This becomes a ritual, a regular, repeating practice that sets me up for success.

For you, it might be Sunday evening. It might be Friday afternoon as you’re wrapping up the work week. Find what works for your rhythm.

Step 4: Execute Without Deliberating

This is the hardest part for some people.

Once you’ve pre-decided, trust the decision.

Don’t stand in front of the wardrobe on Monday morning and reconsider. Don’t second-guess yourself. You already made the decision when your mind was clear. Now just execute.

Monday: grey shirt.
Tuesday: blue shirt.
Done.

The goal isn’t perfection. The goal is reducing friction.

What This Frees You to Focus On

Here’s what I’ve noticed since I started pre-deciding more of my week:

I have more energy for the decisions that matter.

I’m less mentally exhausted by midday.

I’m more present with my family because I’m not constantly low-level stressed about what comes next.

I make better decisions about my priorities because I’m not depleted from fifty micro-decisions before breakfast.

Pre-deciding the small things creates space for me to engage fully with the big things.

And that’s the whole point.

The Sunday Night Advantage

There’s something almost sacred about Sunday evening.

The week is ahead of you. You’re rested (hopefully). You can see the whole picture, what’s coming, what needs attention, what you can prepare for.

It’s the perfect time to set yourself up for success.

Ten minutes of intentional pre-deciding on Sunday night can save you hours of decision fatigue during the week.

So tonight, or next Sunday, try this:

• Open your wardrobe and pick your outfits for the week
• Look at your calendar and decide your top 3 priorities
• Think about meals and pre-decide what you’ll eat (or at least a few key meals)

Decide once. Execute all week.

Your Monday-morning self will thank you.

Reflection Questions

1. What small, repetitive decisions drain your energy every day? Make a list.
2. If you could pre-decide one thing for the entire week, what would have the biggest impact? Your wardrobe? Your meals? Your morning routine?
3. When is your best time to pre-decide? Sunday evening? Friday afternoon? Saturday morning?
4. What’s one decision you make every day that doesn’t actually deserve the mental energy you give it?
5. If you freed up mental energy by pre-deciding the small stuff, what would you use that energy for instead?

Let me know your thoughts. Do you already pre-decide parts of your week? What’s worked for you?
