A study of final-year students at Pomona College in the U.S. has found that thinking that something is about to come to an end can actually make us value it more. The study took place six weeks before the students' graduation. Every day for a fortnight they were asked to write about their college experiences, including the activities they participated in. The experiment was designed so that some of the students thought about graduation as a far-off event and some thought about it as occuring very soon. Those who thought about graduation coming soon participated in more college activities i.e. when they thought about their time at college coming to an end they wanted to make the most of it.
