Want to crush someone's hopes and dreams? Use your imagination. A new study suggests that people are likely to give up their ambitions only after they're given scenarios of all the ways they could horribly, horribly fail.

By toying with the minds of ambitious young college kids, the psych department at the University of Ohio at Lima was able to figure out exactly what to say to make people abandon their dreams. Analysts (or us, anyway) hope this information can be used to nip potential failures in the bud, since toiling away at something you're bad at not only wastes time, but leads to frustration, career plateaus and Paris Hilton movies.

Researchers culled a group of students studying to be psychologists, divided them up, and basically taunted their career aspirations in three different ways. The study deduced that just telling people they'll fail isn't enough -- it helps to paint "a very vivid picture" of said failure.

So the next time your nephew says he wants to be Spider-Man when he grows up, don't just tell him that superheroes aren't real. Tell him that he's going to end up as a mascot at Six Flags, taking pictures with tourists for dollars, occasionally taking off his mask to smoke Kools underneath the tilt-a-whirl.
