Attention degrades over the course of the day. This is not a motivational claim. It is a measurable curve. The hour you spend on hard work at 9am is not the same currency as the hour you spend on hard work at 4pm, no matter how the calendar prices them.
Honest scheduling treats the morning as scarce. Deep work first, meetings in the afternoon, admin in the trough. Reversing the order is a quiet act of self-sabotage that most teams perform out of habit.
Track your own curve for a week before you trust anyone else’s prescription. The shape is personal. The principle — that attention is a depleting resource and not a constant — is not.
