Whether your to-do list is on paper or in digital planning platforms, unfinished tasks always roll over from day to day. We procrastinate, saying it will be done tomorrow, the task was too ambitious or any other reason to push it over.
As the list keeps piling up, the growing number of incomplete tasks will eventually weigh us down. In psychology, this feeling has a name; the Zeigarnik Effect, named after the psychologist who conducted research on this concept.
