It is 5pm.
Someone just asked what’s for dinner, and your brain has completely left the building.
Not because you’re indecisive. Not because you haven’t thought about it. You’ve thought about it four times since noon.
Your brain is just done. And it was done before anyone mentioned food.
This is not a personality trait
Decision fatigue is a documented phenomenon. A 2025 integrative review in Frontiers in Cognition confirms that the human brain’s capacity for decision-making degrades over the course of a day. Every choice you make draws from the same finite pool — and by 5pm, most moms have already made hundreds of decisions nobody counted.
What’s for dinner is not the problem. It’s just the decision that showed up last.
What you’ve already decided today
Wake the kids up or give them five more minutes and do the late math. What everyone’s eating for breakfast. Whether the dentist appointment can wait. Whether to respond to that email now or let it sit. What needs to come from the store. Whether to say something about the permission slip. Whether the weird car noise is worth worrying about.
None of those showed up on a list. None took more than thirty seconds. But they all cost something.
Why it shows up as a short fuse, not tiredness
Decision fatigue doesn’t always feel like exhaustion. It often shows up as irritability. Snapping over small things. Saying “I don’t care, you pick” about things you actually do care about — because finding out what you want takes more than you have left.
If you’ve ever felt guilty for being short with your kids at the end of a day where nothing especially hard happened — this might be why. The day wasn’t objectively hard. It was just relentlessly full.
You’re not impatient. You’re depleted.
What actually helps
The issue isn’t that you’re bad at deciding. It’s that most people never sort their decisions before they start making them. Some things need your full attention. Most can be delegated, batched, deferred, or decided once and applied permanently.
The Decision Filter is a free, five-minute tool for doing exactly that — a quick sorting process so you stop treating every decision like it costs the same. It’s not a planner. It’s a filter for the constant stream that’s draining you before dinner even comes up.

You’re not bad at decisions. You’re making too many of them, for too many people, with no system to sort them. That’s a design problem — and design problems have solutions.
