Those troubled souls who vent their grievances on paper are on to something, found Ohio State University psychologist Richard Petty, Ph.D., and his colleagues
. In one of their studies, high school students who were asked to write down thoughts about body image and then rate their own figures were only affected by their thoughts if they were asked to hold on to their papers and review them. Those who were told to chuck the papers in the trash showed no difference in how they rated themselves
, regardless of whether they confessed positive or negative thoughts. "By physically throwing away or protecting your thoughts, you influence how you end up using those thoughts," Petty said. So write them down and then—this is key—be sure to shred them, burn them, toss them in the compactor or drag them into the trash can on your desktop—and empty it.
