Why Decision Fatigue Is Draining You More Than the Work Itself
And how to reclaim your energy without scaling back your ambition.
You probably know the feeling: you finish a marathon day at work, but it’s not the emails, projects, or meetings that leave you exhausted—it’s the constant deciding. Should you greenlight that project? Reschedule the meeting? Approve your employee’s time-off request? And that’s before you even tackle the personal decisions waiting at home—what’s for dinner, which bills to prioritize, or whether you’ll make it to the gym.
This exhaustion has a name: decision fatigue.
Coined by social psychologist Roy Baumeister, the term describes the mental depletion that builds up after making too many choices throughout the day.¹ While burnout is often attributed to workload, research suggests that the number of daily micro-decisions you make might be just as draining as the work itself.²
For high-achieving women in leadership roles, decision fatigue can be especially acute. You’re not just making choices for yourself—you’re often making them for your teams, projects, and families. The hidden cost? Slower thinking, impaired judgment, and a creeping sense of exhaustion that no amount of coffee seems to cure.
But here’s the good news: by learning how to recognize, prevent, and manage decision fatigue, you can preserve your mental energy for what really matters—leading well and living fully.
Section 1: The Psychology of Decision Fatigue
At its core, decision fatigue is the gradual decline in the quality of decisions after a long session of decision-making.³ Each choice—big or small—consumes a slice of cognitive energy. Eventually, your brain starts looking for shortcuts:
Impulse choices: Saying “yes” too quickly just to get the decision off your plate.
Avoidance: Postponing a decision because the thought of making one more feels unbearable.
Defaulting: Going with the safest or easiest option, even if it’s not the best one.
Research has shown that judges, for example, were more likely to deny parole later in the day after making dozens of prior rulings.⁴ The takeaway: your brain doesn’t have an endless well of willpower or rationality. Once it’s tapped out, the quality of your decisions—and your leadership—can take a hit.
Action Step: Start tracking when your decision-making feels sharpest during the day. Many leaders find their mornings are strongest, making it the ideal time for high-stakes calls. Save routine or low-impact decisions (like approving minor requests or scheduling meetings) for the afternoon when your mental reserves dip.
Section 2: How Decision Fatigue Shows Up in Your Daily Life
1. You procrastinate on small decisions.
Decision fatigue doesn’t always show up in the big moments. More often, it creeps in as hesitation over the smallest choices. Research shows that when cognitive resources are depleted, people delay or avoid decisions altogether, even if the stakes are low.¹
Workplace scenario: You’ve spent the entire day reviewing budget approvals, answering Slack messages, and navigating back-to-back meetings. At 6 p.m., one last email comes in: “Which headshot should we use for the staff newsletter?” It’s a two-minute decision, but instead of replying, you leave it unread for days. By the time you finally respond, you’re frustrated at yourself for letting something so minor take up space in your mind.
Why it matters: Procrastination on small decisions is one of the earliest signals that your mental reserves are running low. Left unchecked, these bottlenecks create unnecessary stress for you—and slowdowns for your team.
2. You default to the easiest option—even if it’s not the best one.
When your decision-making energy is drained, your brain looks for shortcuts. Psychologists call this decision simplification—you’re more likely to choose the path of least resistance than the one requiring careful evaluation.²
Workplace scenario: You’re reviewing vendor proposals for a new contract. The first few get your full attention, but by the tenth, you find yourself thinking, “Let’s just stick with the same company we used last year.” It feels easier than digging into the details—but it also means you might miss out on better pricing or innovative solutions.
Why it matters: Choosing the easiest option might keep things moving in the moment, but it undermines long-term results. For high-achieving women who pride themselves on strategic thinking, defaulting to the quick fix can chip away at both effectiveness and confidence.
3. You snap at people over minor requests.
Decision fatigue doesn’t just cloud judgment—it thins your patience. As cognitive load builds, the brain has fewer resources left for emotional regulation.³ This is why even small, reasonable requests can feel like interruptions or personal attacks when your decision-making “bandwidth” is spent.
Workplace scenario: It’s 4:45 p.m., and you’re finally catching up on your own to-do list after a day of managing crises and approvals. A direct report pokes their head in to ask, “Do you want me to copy you on this email?” Normally, you’d smile and give a quick answer. Today, you feel irritation rising, and your reply comes out sharper than intended. Five minutes later, you regret it—but the frustration wasn’t really about the email; it was about your depleted mental state.
Why it matters: These moments may seem small, but they accumulate. When decision fatigue makes you irritable, relationships with colleagues and direct reports can fray. For women leaders especially—who often feel pressure to balance authority with approachability—snapping under stress can feel doubly costly.
4. You second-guess decisions you’ve already made.
Another hallmark of decision fatigue is replaying choices long after they’re settled. Instead of moving forward, you loop back, questioning whether you made the “right” call. This doesn’t come from lack of ability—it comes from depleted cognitive energy. When your brain is tired, confidence in judgment slips, and self-doubt creeps in.⁴
Workplace scenario: You’ve already finalized the agenda for next week’s leadership retreat. But that night, as you’re trying to unwind, you keep scrolling through the slides, wondering if you should’ve given more time to team-building or shortened the budget review. The next morning, you tweak the agenda again—even though the first version was perfectly fine.
Why it matters: Constant second-guessing drains more energy than the original decision itself. For high-achieving women, it also feeds into imposter syndrome: the sense that you can’t trust your instincts, even though your track record proves otherwise. Over time, this cycle creates mental clutter and delays progress.
5. You avoid making decisions altogether.
At its peak, decision fatigue can push you into avoidance—either deferring choices, over-delegating, or ignoring decisions entirely. This isn’t laziness; it’s a protective mechanism. When the brain is overtaxed, it starts to perceive even simple decisions as overwhelming, leading to withdrawal.⁵
Workplace scenario: Your team is waiting for your input on next quarter’s project priorities. Instead of choosing, you push the discussion to next week’s meeting. When pressed, you respond with “Why don’t you all decide what makes the most sense?” While delegation can be healthy, in this case it comes from exhaustion, not strategy—and your team leaves unclear on the path forward.
Why it matters: Chronic decision avoidance can erode trust. Teams rely on leaders for clarity and direction, and when that clarity is delayed, it creates frustration and inefficiency. For high-achieving women, who are often balancing multiple responsibilities at once, avoiding decisions can quietly undermine both authority and progress.
Recognizing these patterns is the first step. Decision fatigue doesn’t announce itself loudly—it sneaks in through procrastination, snap reactions, second-guessing, or avoidance. Left unchecked, it can quietly chip away at your confidence, relationships, and leadership effectiveness. The good news? Just as decision fatigue builds through small choices, it can also be prevented through intentional habits that protect your mental energy.
In the next section, we’ll look at practical strategies to reduce the load, conserve your decision-making power, and make room for the decisions that truly matter.
Section 3: Strategies to Prevent Decision Fatigue
1. Automate low-stakes decisions wherever possible.
Every choice you make uses up a slice of your mental energy. One of the most effective ways to protect that energy is to remove small, repetitive decisions from your daily routine. Research on ego depletion shows that simplifying predictable choices—what to wear, what to eat, how to start your day—preserves willpower for the decisions that matter most.⁶
Workplace example: Instead of starting each morning debating your calendar setup, create a standing routine: review emails for 30 minutes, prioritize your top three tasks, then check in with your team. Similarly, pre-set approval thresholds with your staff so they know what they can greenlight without you. This way, you’re not repeatedly pulled into the same minor calls.
Why it matters: Automating the small stuff frees you to focus on high-value decisions that require creativity, judgment, and strategic thinking. For high-achieving women in leadership, this isn’t about rigidity—it’s about designing smart systems that reduce friction and prevent burnout.
2. Set boundaries on when (and how) you make decisions.
Not all hours in the day are created equal. Research on circadian rhythms shows that mental energy peaks and dips at predictable times—for most people, focus is strongest in the first half of the day and weakens in the late afternoon.⁷ If you’re making your most critical choices at 5 p.m., you’re working against your brain’s natural rhythm.
Workplace example: A director schedules her weekly budget approvals for Monday mornings when her mind is sharpest, and reserves late afternoons for lighter tasks like email or routine check-ins. She also sets a boundary with her team: urgent decisions can be flagged anytime, but non-urgent requests should be submitted by 2 p.m. This ensures she’s tackling important choices before her decision-making reserves are depleted.
Why it matters: Boundaries around timing protect both energy and quality. For women leaders who often face constant requests, this structure communicates clarity to their teams and ensures their best cognitive resources are directed toward the most impactful work.
3. Use decision frameworks to reduce mental load.
Decision fatigue thrives in ambiguity. The more open-ended a choice feels, the more energy it requires. Creating clear criteria or frameworks transforms complex decisions into structured evaluations, lowering the cognitive burden.⁸ Leaders who rely on systems—checklists, templates, scoring rubrics—preserve mental energy while also building consistency across their teams.
Workplace example: When reviewing vendor proposals, instead of starting from scratch each time, you establish a scoring rubric with weighted categories: cost, quality, reliability, and alignment with school needs. Rather than juggling every variable in your head, you follow the framework. The decision becomes faster, more transparent, and easier to explain to stakeholders.
Why it matters: Frameworks reduce both overthinking and regret. They give leaders confidence in their process, minimize bias, and make delegation smoother since others can apply the same criteria. For women in leadership—who often face greater scrutiny around their choices—frameworks provide a defensible way to show that decisions were thoughtful, fair, and grounded in standards.
4. Limit your decision inputs.
The human brain wasn’t designed to process endless streams of data. Studies on information overload show that the more options and inputs we have, the harder it becomes to choose—and the less satisfied we feel with our choices.⁹ Every unnecessary opinion, report, or menu of options adds to the drain on your cognitive energy.
Workplace example: Instead of asking your team for “all possible ideas” for an upcoming initiative, you set a clear request: “Bring me your top three recommendations, ranked in order of impact.” By narrowing the scope, you reduce the noise and make it easier to evaluate. Similarly, unsubscribing from nonessential newsletters or muting Slack channels can cut down on daily decision clutter.
Why it matters: Reducing inputs helps you stay focused on the most relevant information, protecting you from analysis paralysis. For high-achieving women—who are often expected to weigh in on everything—limiting decision inputs isn’t about disengagement; it’s about safeguarding the clarity needed to lead effectively.
5. Prioritize recovery—because rest restores decision-making power.
Decision fatigue isn’t solved by sheer willpower. The brain, like any muscle, needs rest to function well. Neuroscience research shows that sleep, breaks, and even brief periods of disengagement allow the prefrontal cortex—the center of executive decision-making—to reset.¹⁰ Without recovery, the cycle of depletion only compounds.
Workplace example: A department head builds short recovery rituals into her day: a 10-minute walk after lunch, a rule of not scheduling meetings back-to-back, and a commitment to shutting her laptop by 7 p.m. She also protects her sleep as fiercely as she protects her calendar, knowing that late-night email sessions only rob her of sharper judgment tomorrow.
Why it matters: Rest is not indulgence—it’s strategy. Leaders who prioritize recovery make clearer, faster, and more confident choices. For women who are often juggling demanding professional roles with personal responsibilities, recovery is the foundation that sustains long-term impact without burning out.
Decision fatigue isn’t inevitable. With the right systems, boundaries, and recovery habits, you can reclaim the clarity and confidence that endless choices threaten to erode. These strategies don’t just lighten your cognitive load—they create space for the kind of decisions that define strong leadership. By treating decision-making as a resource to be managed, you position yourself to lead with sharper focus, steadier patience, and a renewed sense of control.
Final Thoughts
Decision fatigue may be invisible, but its effects are anything but. From procrastination and irritability to second-guessing and avoidance, the signs creep into daily life in ways that drain confidence and strain relationships. For women in leadership, the stakes are even higher: the constant demand to balance authority with approachability means that every slip in patience or clarity can feel amplified.
The good news is that decision fatigue isn’t a fixed reality—it’s a signal. By automating low-stakes choices, setting clear boundaries, relying on frameworks, limiting inputs, and prioritizing recovery, you can protect your decision-making power where it matters most. These aren’t just productivity hacks; they are leadership practices that safeguard your influence, preserve your energy, and ensure that the choices shaping your career and your team are made with clarity, not exhaustion.
At its core, leadership isn’t about making every decision. It’s about making the right decisions—and doing so with consistency, confidence, and care. By recognizing the signs of decision fatigue and proactively managing your mental energy, you give yourself the greatest advantage of all: the ability to lead with intention.
