Identify at least three body language messages that project a positive attitude?

Talking with your hands is one way that can emphasize what you say as well as showing you're comfortable & easy going. Eye contact is another key as well as keeping your head up, but no need to stare themdown either; look around occasionally. Lastly, a steady paced speech. Not talking too fast or too slow & with breaths in between.
Hope this helps!! :)
