Burnout or just tired? Four differences that actually separate them
Tired resolves with rest. Burnout doesn't, and it changes what you feel about work rather than just how much energy you have for it. Here's how to tell which one you're in.

"I think I'm burnt out" gets said a lot, usually in weeks that were simply long. The distinction matters because the two conditions respond to completely different things: one of them gets better on a vacation, and one of them doesn't.
The World Health Organization classifies burnout as an occupational phenomenon — something that arises from chronic workplace stress that hasn't been successfully managed — rather than a medical condition. It describes three components: exhaustion, mental distance or cynicism about the job, and reduced sense of effectiveness.
That third one is the giveaway, and it's the one people skip.
Four practical differences
1. Rest works, or it doesn't. Tired is a debt. Sleep, a weekend, a week off, and the balance clears. Burnout survives the vacation — you come back rested and the dread arrives before the second morning. If a genuine break didn't change how Sunday evening feels, that's the clearest signal there is.
2. It's energy, or it's caring. Tired says I don't have the energy for this today. Burnout says I can't make myself care about this anymore. The second is more specific and more alarming, and it usually shows up first as a flatness about outcomes you used to find satisfying.
3. It's everywhere, or it's here. Tired doesn't discriminate — you're low on energy for work, hobbies and friends alike. Burnout is often strangely local. People deep in it can be exhausted and cynical from 9 to 6 and completely alive at 7pm doing something else. If your energy returns the moment you close the laptop, the problem probably isn't your energy.
4. Your competence feels different. This is the component people miss. Burnout comes with a shrinking sense of being any good at the thing — work that used to take an hour takes three, and the output feels worse to you even when nobody else notices. Tired makes you slow. Burnout makes you doubt.
What each one actually needs
If it's tiredness, the answer is boring and it works: sleep, fewer commitments for two weeks, and time away from screens in the evening. It resolves.
If it's burnout, rest alone won't fix it, because the input hasn't changed. What tends to move it is a change in the conditions — the workload, the amount of control you have, the recognition, or the fit between the job and what you actually want to be doing. That can mean a conversation with a manager, a reshaped role, or in some cases a different job. But it's worth being precise: the fix is rarely leaving. The fix is changing the specific thing that's grinding.
Before you decide it's the job
Two things quietly imitate burnout and are worth ruling out first.
Attention that's been fragmented all day. If your focus is broken up by notifications from the moment you wake, the exhaustion at 6pm may have very little to do with the work itself. That's a different problem with a different fix.
A mismatch that's been there for years. Some people describe burnout when the accurate description is that the job was never right and they've been absorbing that cost quietly for a long time. Those feel identical from the inside and need opposite responses.
Two things worth doing
The should you quit your job quiz separates the three cases above — a job that's grinding you, attention that's been fragmented, and a fit that was never there — because they look the same and don't want the same answer. The dopamine quiz looks specifically at the attention side, which is the one people most often mistake for burnout.
One last thing, said plainly: if the flatness has been there for months, extends past work into things you used to enjoy, or comes with changes in sleep or appetite, that's worth raising with a doctor or therapist rather than solving with a quiz. This is a topic where getting the category right matters, and a professional is much better placed to help you do that than anything on the internet.
