Flies Over Lions: You're Tired of the Wrong War

There is a particular kind of exhaustion that has nothing to do with how much you've done.

You know the one. You wake up after eight hours of sleep and the tiredness is already there, waiting for you — sitting on the edge of the bed before you've even opened your eyes. You ran no marathons. You moved no mountains. You answered some emails, drove somewhere, had a conversation that went slightly sideways, noticed something someone said at lunch that you're still turning over at eleven at night. And yet you feel as though you have been at war.

You have been. Just not the war you think.

In the clinic, I see this constantly — people who are genuinely capable, genuinely hardworking, who arrive describing burnout that doesn't quite fit the clinical picture. They're not doing too much. They're doing the *wrong* kind of fighting. There's a distinction, and it matters enormously.

The psychologist Roy Baumeister's research on ego depletion — now refined and debated, but the core observation still stands — showed that willpower and self-regulation draw from a shared cognitive resource. Every time you make a decision, manage an emotional reaction, or suppress an impulse, you spend from that account. The account is not bottomless. What depletes it fastest is not sustained effort toward something meaningful. It's low-grade, repetitive friction. The small provocations you feel obligated to respond to. The person at the table who made a comment designed to diminish you. The group chat that is nominally professional but is actually a performance. The slow driver you followed for ten minutes while your blood pressure quietly climbed.

These are the flies. Not lions.

The problem is that our nervous systems don't discriminate well between threats. The amygdala — that ancient, efficient alarm system lodged in the brain's limbic region — responds to social threat the way it responds to physical danger. Being ignored in a meeting and being stalked through a forest produce, neurologically, overlapping signatures. Your body mobilizes. Cortisol rises. Attention narrows. You are, physiologically, preparing to fight or flee — and all you actually did was read a passive-aggressive reply to an email you sent on Wednesday.

If this happened once, you'd recover. But most of us do this fifteen, twenty, forty times a day. We enter every micro-conflict fully armed. We carry grievances from the morning into the afternoon and the afternoon into the evening. We rehearse arguments with people who aren't in the room. We compose the perfect response to something that happened three days ago. We are perpetually mobilized against threats that, honestly, didn't need a war.

The ancient Stoics had a framework for this — though they were, admittedly, less warm about it than I prefer to be. Marcus Aurelius wrote: *You have power over your mind, not outside events. Realize this, and you will find strength.* What he meant, practically, is that the stimulus and your response to it are two separate things, and somewhere in the gap between them lives every hour of your life you are currently giving away for free.

Here is the question I ask clients when they describe this kind of depletion: *Was this battle worth your best energy?* Not: was the other person wrong? Not: did you have the right to be angry? Of course they were, and of course you did. That's not the question. The question is whether the energy you spent on it was the right trade.

A rude driver took three minutes of your actual life and approximately forty minutes of mental real estate. A colleague's throwaway comment during a meeting is still costing you at eleven PM. Someone on the internet said something wrong, and you're in the replies. None of these are lions. None of them required you to unsheath everything you have.

This is not a call to become passive. I am constitutionally incapable of advising anyone to simply accept mistreatment with a beatific smile — that's not equanimity, that's suppression in prettier clothes, and it will find its way out eventually. There are battles worth every drop of blood you have. The ones that touch your actual values, your real people, your true work. Fight those with everything. Rest for those. Conserve for those.

The practice, then, is discrimination. Before you engage — before the cortisol floods and the jaw tightens and the mental rehearsal begins — one breath, one question: *Is this a lion or a fly?*

If it's a fly, you have
