Tell me if this is you. Morning: unstoppable. Afternoon: one email and you’re done. And the voice in your head says you got lazy, or lost focus, or just aren’t built for this anymore.
A study published last month in Communications Psychology tracked 1,088 people through their actual days. The finding that stopped me: people who were thinking faster than usual in the morning had a harder time pushing through fatigue later. Researchers call that ability “fatigue override,” and it’s a resource, not a personality trait. You can spend it. A great morning is often where it goes.
So your 3 PM wall isn’t evidence you did something wrong. It’s the bill for a morning you did well.
If you’d like to see where your capacity gets spent first, the Capacity Pattern Quiz is in my bio.
