Duration Effect

Ask people to estimate how long a task felt, and their answer depends far less on the clock than on how the task ended and whether it was interesting. Pleasure shortens; pain stretches; a good ending forgives a long ordeal.

The mind does not store time the way a clock does. It stores scenes — peaks and endings mostly — and reconstructs the duration from those. Two minutes of agony can outweigh twenty minutes of ease; the ease is barely filed.

This is why the last five minutes of anything — the meal, the meeting, the holiday, the day — carry disproportionate weight in memory. The ending is what the archive keeps.

So design endings. Finish the hard task with the easiest part. Close the visit with the warm exchange. End the workday by noting what went well, not with the unfinished dread. You cannot control the whole length of anything. You can almost always control how it ends — and the ending is what stays.
