ELI5: Why is it so easy for us to concentrate for hours on movies, video games, etc but so hard to maintain our attention span for minutes on academic activities?

Movies, games etc provide an instant dopomine release, which encourages you to continue (instant gratification). When studying you dont get the dopamine release until a lot longer, when you ace a test or feel proud of yourself for studying all day.
