📘 Why does starting feel harder than continuing?

What you’ll learn

1. Effort Tracks the Distance LeftSee the start as the point of maximum remaining distance, and meet the evidence that effort varies with that distance rather than with the work itself.Hull's rats ran faster the nearer they got to the food, and café customers bought coffee faster the fuller their card got — a 20% fall in interpurchase time for a drink whose price, taste and reward never changed.
2. The Head Start That Was Not ThereUse the illusionary-progress experiment to separate how much work is left from how far away the goal looks.Two cards requiring the identical ten purchases were completed 15.6 and 12.7 days apart, the difference being two stamps that were given away — which is why the fixes that work on a hard start shrink the apparent distance rather than shout at the person.
3. A Task Already Begun Pulls You BackTell the surviving half of the Zeigarnik–Ovsiankina story from the half that did not survive, and locate where a running task keeps its state.A century on, the memory advantage for unfinished tasks is gone at 49.16% against a chance value of 50, but the tendency to resume them holds at 66.79% — and what pulls a person back is often something left visible in the room rather than anything in their head.
4. Where the Story BreaksHold the two findings that complicate the course's own thesis, and know which part of it was never tested.Motivation may dip lowest around the halfway mark rather than at the start, and a start landing on the first day of a week is measurably cheaper than the same start two days earlier — while every gradient here was measured on goals with a countable distance, which most real work does not have.
