Next time you have a big presentation or meeting at work, spend a few minutes in the bathroom beforehand yelling “clear eyes, full hearts, can’t lose” in the mirror. Then walk out of there looking as determined as you can. A new study from University of Tennessee, showed when you put on a “game face,” it really can help you perform better.

The researchers say, quote, “‘Game face’ may not only improve performance in cognitive tasks, but could also lead to better recovery from stress.” You’ll be sharper in meetings and if someone throws out something unexpected, you’ll be able to handle it better.

You may want to find a more private bathroom to put your game face on. You don’t want people stealing your secret weapon, or looking at you oddly.
