Why Your Job Feels Harder Than It Should

You’re good at your job. You know you are. But by 3pm, you’re exhausted in a way that doesn’t match what you actually did. No heavy lifting. No crisis. Just… a normal day. And yet you’re drained.

Something is making this harder than it should be. And it’s probably not what you think.

The thing making your job feel impossible usually isn’t the work itself. It’s everything around the work that nobody counts as work.

The Problem

There’s a version of workplace exhaustion that has nothing to do with the actual tasks on your plate. You didn’t do anything extraordinarily difficult today. You didn’t work unusually long hours. You just did your normal job — and somehow it ate everything you had.

This feeling is incredibly common, and almost nobody talks about it honestly, because it doesn’t have an obvious cause. You can’t point to the thing that drained you. It wasn’t one big thing. It was a hundred small things, each one barely noticeable on its own, that added up to a weight nobody anticipated.

The culprit is almost never the core work. It’s the friction around the core work. The switching. The deciding. The interpreting. The small, invisible cognitive labor that fills the gaps between the tasks you’d actually put on a to-do list — and that never shows up in any job description.

This friction is so woven into the fabric of modern knowledge work that most people have stopped noticing it. It just feels like “how work is.” But it isn’t inevitable. It’s a design problem — and like most design problems, it can be reduced once you understand where it’s actually coming from.

Why this happens to knowledge workers

Knowledge work is uniquely vulnerable to this kind of invisible friction because it depends so heavily on cognitive resources — and cognitive resources are finite in a way that physical energy isn’t. You can push through physical tiredness with caffeine and willpower. You can’t push through cognitive depletion the same way. Once the mental bandwidth is used up, the quality of your thinking drops, and no amount of effort can fully compensate.

Research suggests that the human brain makes thousands of small decisions in a single workday — most of them below the level of conscious awareness. Which email to open first. How to interpret an ambiguous message. What to prioritize when two things feel equally urgent. Whether this task is worth doing now or later. Each decision is tiny. But each one costs a small amount of mental energy, and the costs accumulate.

There’s also the problem of context switching — moving between different types of work, different projects, different modes of thinking. Research suggests that each switch carries a cognitive cost that’s larger than people expect. It’s not just the time it takes to shift. It’s the mental “loading” — the effort of remembering where you left off, re-entering the mindset of a different task, and rebuilding the thread of your thinking. Do this twenty or thirty times a day, and the cumulative cost is enormous.

Many people find that this explains a gap they’ve felt for years but never understood: why a day full of “easy” tasks feels more draining than a day spent on one hard thing. The hard thing required deep focus, but it didn’t require constant switching. The easy tasks were individually simple, but the act of moving between them burned through cognitive resources faster than any single task would have.

What Most People Try

The first and most common response is to try to be more efficient. If the day feels too heavy, the solution must be to get things done faster. Better tools. Sharper focus. Tighter routines. And efficiency matters — but it addresses the wrong variable. The problem usually isn’t how long each task takes. It’s how many times you have to stop, shift, and restart.

Others try to reduce the total number of tasks. Cut the meetings. Decline the unnecessary requests. Simplify the plate. This helps at the margin, but it often misses the deeper issue: even a small number of tasks can be exhausting if they’re fragmented, ambiguous, or constantly interrupting each other.

A third approach is to power through with caffeine, willpower, and a strong sense of obligation. Push past the tiredness. Finish the day. Rest later. This works in the short term — but research suggests that consistently pushing through cognitive depletion doesn’t just make you tired. It degrades the quality of your decisions and your thinking in ways that are hard to notice while they’re happening. You feel like you’re functioning. You’re not functioning as well as you think.

Some people try to fix it with better work-life balance. More sleep. More exercise. Weekends off. These things genuinely help with recovery. But they don’t change the structure of the workday itself. If the workday is still generating the same amount of invisible friction, you’ll keep recovering from it every night, and it’ll keep draining you every morning.

What most of these approaches miss is that the problem isn’t how hard you’re working or how much you’re working. It’s the structure of how the work is arranged — and structure is something you can actually change.

What Actually Helps

1. Identify where your energy is actually going — not where you think it’s going

Most people, if you asked them what drained them today, would point to the big things. The hard meeting. The complex project. The stressful conversation. But research suggests that these are rarely the main culprits. The main culprits are the small, invisible things — the context switches, the ambiguous messages, the tiny decisions that pile up without anyone noticing.

The fix is to actually track it. For one day, every time you feel a small internal “ugh” — a moment of resistance, a flicker of friction — note what you were doing. Don’t analyze it. Just write it down. At the end of the day, look at the list.

Most people who do this are surprised. The friction isn’t where they expected it to be. It’s in the transitions. It’s in the ambiguity. It’s in the moments where they had to stop and figure out what to do next, rather than just doing it. Once you can see where the energy is actually going, you can start making targeted changes — instead of guessing.

How to start: Pick one day this week. Keep a simple list — even just a notes app on your phone. Every time something feels harder than it should, jot down what it was. One word is enough. At the end of the day, look for the pattern.

2. Reduce decisions by creating defaults for the small stuff

A huge portion of the invisible friction in knowledge work comes from low-stakes decisions that eat up mental energy out of all proportion to their importance. Which task first? How to respond to this email? Should I handle this now or later? These decisions don’t feel significant in the moment. But collectively, they create a constant low-grade drain on the brain’s decision-making capacity.

The most effective countermeasure is to eliminate as many of these decisions as possible by replacing them with defaults. A default is a pre-made choice that you follow automatically unless there’s a specific reason not to. What’s the first thing you do every morning? Make it a rule, not a choice. How do you respond to routine requests? Write a template. When do you check email? Set a time and stick to it.

Defaults don’t have to be perfect. They just have to be good enough — and they have to be decided in advance, so that in the moment, there’s nothing to decide. The goal isn’t to optimize every micro-decision. It’s to remove as many of them as possible from your mental bandwidth, so that the bandwidth you do have is available for the decisions that actually matter.

Many people find that even a handful of well-chosen defaults — three or four — meaningfully reduce the feeling of cognitive weight throughout the day. The tasks haven’t changed. The number of hours hasn’t changed. But the friction has dropped, and the day feels lighter as a result.

3. Batch similar tasks together to reduce context switching

Context switching is one of the most expensive forms of invisible friction, and it’s also one of the most fixable. The fix is deceptively simple: group similar tasks together and do them in a single block, rather than scattering them throughout the day.

Emails in one block. Calls in another. Deep thinking in another. Creative work in another. The specific groupings matter less than the principle: each block requires only one kind of mental mode, and you stay in that mode for as long as possible before switching.

This sounds obvious. But in practice, most people’s days are structured around interruptions rather than blocks. An email arrives — you answer it. A message comes in — you switch to it. A meeting pops up — you join. Each one is a context switch, and each one costs you something.

Research suggests that it takes an average of over twenty minutes to fully re-engage with a task after an interruption. If you’re switching tasks ten or fifteen times a day, you’re losing hours — not to the tasks themselves, but to the cognitive cost of moving between them. Batching doesn’t eliminate that cost entirely, but it reduces the number of switches dramatically, and with it, the invisible weight that makes the day feel harder than it should.

The Takeaway

Your job feeling harder than it should isn’t a sign that you’re struggling or that you’re not cut out for it. It’s a sign that the invisible friction in your workday is higher than it needs to be — and that friction is almost always reducible.

You don’t have to overhaul everything. Start by seeing where the energy is actually going. Then pick one or two places where the friction is highest, and make a small change. A default here. A batch there. A single interruption-free block in the middle of the day.

The work is the same. The hours are the same. But the way it feels — and the way it costs you — can be genuinely different.
