Is This Why You’re Exhausted by 5 PM? (Hint: It’s Not Just Work—It’s Decision Fatigue)

How to Outsmart Decision Fatigue: 7 Simple Ways to Stop Feeling Drained

You start the day feeling fresh and focused. But by 5 PM, even the simplest choices—like what to eat or whether to go to the gym—feel impossible.

The average adult makes around 35,000 decisions daily—no wonder we’re exhausted.

From the moment we wake up, our brains are in constant decision-making mode:
➡ Hit snooze or get up?
➡ Check the phone or start the day?
➡ What to wear? What’s for breakfast?

Even the smallest choices drain mental energy, overloading our brains before the day is even halfway through.

By dinnertime, the question of “What’s for dinner?” can feel like the final straw.

It’s called decision fatigue—and it happens when our mental energy is depleted from making too many choices throughout the day.

When Willpower Fades

Ever noticed how grocery stores seem designed to wear us down?

By the time we reach the checkout, we’ve already had an internal debate about which snacks to skip, which bread to pick, and why ice cream is definitely off-limits this week. It’s a mental marathon.

So when that chocolate bar stares back at us at checkout, it feels like a reward. Not because we lack willpower—but because we’re mentally exhausted.

After a day filled with “no, no, and no,” the treat at checkout feels like the one yes we’ve earned.

But decision fatigue doesn’t just affect shopping habits—it impacts productivity, health, and overall happiness. It can lead to:

• Procrastination (because deciding feels overwhelming

• Impulse choices (because we just want something easy)

• Feeling stuck (because decisions feel too exhausting to make)

Decision Fatigue Affects Everyone

Even judges are more likely to make harsher decisions at the end of the day.

A study on Arkansas traffic court judges found that as the day went on, the likelihood of dismissing charges decreased—simply because their mental energy was depleted.

Research shows that the more choices we make, the more likely we are to:

• Skip the gym

• Make unhealthy food choices

• Overspend on impulse purchases

The good news? There are simple, everyday strategies to beat decision fatigue—and they make a huge difference.

7 Ways to Outsmart Decision Fatigue and Reclaim Your Mental Energy

1. Prioritize Your Most Important Decisions in the Morning

Mornings are prime decision-making time when our mental energy is at its peak.

✔ Plan to tackle your biggest, most important decisions first thing in the morning—when your brain is fresh.
✔ I picked this up from Zen Habits by Leo Babauta years ago, and it’s completely changed how I structure my day.

2. Plan Tomorrow’s Top 3 Today

Evening planning is a game-changer.

✔ Spend just 3–5 minutes before bed writing down your top three priorities for tomorrow.
✔ This eliminates the “Where do I even start?” feeling and lets you wake up with a clear plan.

3. Put Mornings on Autopilot

Mornings are filled with tiny, energy-draining decisions—so why not eliminate them?

✔ Stick to the same morning routine so you don’t waste brainpower on simple choices.
✔ Lay out your clothes the night before.
✔ Follow a consistent morning rhythm to save energy for bigger decisions later in the day.

4. Simplify Your Closet to Reduce Decision Overload

Ever stare at your closet with no idea what to wear—and feel exhausted before the day even starts?

This is why people like Mark Zuckerberg wear the same thing every day—to reduce decision fatigue.

While we don’t all want to wear a gray t-shirt daily, a capsule wardrobe can help:
✔ Fewer clothes, but ones you love and feel good in
✔ Less time spent deciding what to wear
✔ Less stress in the mornings

5. Use Task Batching

Switching between different tasks drains mental energy fast. Instead, use batching to keep your focus:

✔ Dedicate specific days or time blocks for different types of work (e.g., creative tasks, admin, errands).
✔ Follow a Performer’s Schedule—where you group similar tasks together to stay in the zone.

6. Create Decision-Free Zones

The fewer decisions we make, the more energy we have for what truly matters.

Try these:
✔ I only check email twice a day.
✔ Taco Tuesdays for dinner.
✔ Sunday is meal-prep day.

Meal planning has been life-changing for me—I used to dread the What’s for dinner? question. Now, I follow a set rotation, and dinner decisions are easy.

I also schedule an hour of reading or podcast listening each day—so I never waste time debating what to do next.

7. Use the “2-Minute Rule”

If a decision or task takes less than 2 minutes, do it immediately.

This eliminates mental clutter from tiny decisions piling up.

✔ Answer that quick email instead of saving it for later.
✔ Put away the laundry instead of letting it sit.

When we tackle small decisions immediately, our brain stays clear for bigger priorities.

Cutting the Mental Clutter: Why Too Many Choices Exhaust Us

Ever spent way too long scrolling Netflix, trying to pick something to watch—until you don’t even feel like watching anymore?

That’s decision paralysis. In theory, having options is great—but in reality, too many choices exhaust us.

Or maybe you’ve sat down at a restaurant with a never-ending menu and suddenly couldn’t decide?

🔹 Fewer choices = Less stress.
🔹 Less stress = More energy.

When we eliminate mental clutter, we free up brainpower for what really matters.

As Dumbledore so wisely said in Harry Potter,

It is our choices, Harry, that show what we truly are, far more than our abilities.

The choices we make—especially when we’re drained—define us.

When we cut through the clutter, we create space for what truly matters: more energy, clarity, and focus on what we actually want to prioritize.
