Further studies showed that the willpower mindsets could predict students’ procrastination levels in the run-up to exams – those with the non-limited views showed less time-wasting – and their ultimate grades. When facing high-pressure from their courses, the students with the non-limited views were also better able to maintain their self-control in other areas of life; they were less likely to eat fast food or go on an impulsive spending spree, for example. Those who believed that their willpower was easily depleted by their work, in contrast, were more likely to indulge in those vices – presumably because they felt that their reserves of self-control had already been depleted by their academic work.
