Can the way you stand or sit affect your success？
   This is often discussed in business—"the importance of body language"，noted U.S.news website Business Insider. "It actually has an impact on not just the way others look at us，but also how we actually perform."
   That's perhaps why Harvard Business School professor Amy Cuddy shot to instant fame after giving a TED talk on the subject in 2012.According to The New York Times，Cuddy's speech is among the most viewed TED talks of all time.
   Cuddy and her team study body language，particularly what they call "high-power" and "low-power" poses.Their research showed that standing or sitting in a certain way，even for just two minutes，changes one's body chemistry and self-perception.
   "I wanted to equip people with tools that would help them feel stronger，less fearful，and better able to bring their full，spirited selves to stressful situations like speaking in class，" Cuddy told CNN.
   "High-power" refers to the act of taking a posture of confidence，even when you don't feel very confident.Typical high-power poses are about opening up.You stretch and expand your body to take up as much space as possible.For example，bosses are doing high-power poses when they lean back in their chairs，put their hands behind their heads，and kick their feet up onto their desks.Meanwhile，people take low-power positions when they're feeling helpless or defeated.They close up，wrapping their arms around themselves and tucking their limbs in.
   "This isn't about what your body language is communicating to others；it's about what your body language is communicating to you.Your body language is changing your mind，which changes your behavior，which changes your outcomes，" said Cuddy.
   The best-known high-power pose is nicknamed the "Wonder Woman" pose.You just stand tall with your chest out and your hands on your hips.Why not give it a shot，and see whether you feel more confident than before？
