5. Keep your head upright
Generally, people with introverted personalities talk and walk with their heads down. They also tend to bow when talking to someone. These postures can be often interpreted as a lack of self-esteem. And to be frank, they often are. On the other hand, people who walk and talk with their heads raised can seem confident and secure. If a person is honest and has nothing to hide, they generally walk and talk with their heads upright.
