It’s not something you have, it’s something you earn, and you can learn how to earn it. There are some good tips above and some lousy ones. Not using your hands is like speaking with a gag. You can control a group of people like an orchestra, with looks, nods, shakes of the head, moving forward and back in your seat, putting things on the table, opening or closing hands, bigger gestures, looking at the floor or the ceiling, or out of the window. People are visual things, play on that.
Think back to your school days. There were the teachers who took a while to get calm before starting. Then there was the seen-it-all language teacher. She walked in, messed around with her stuff, found a working board pen, opened her book at page whatever then moved to center stage, swept both arms out as she stamped a foot and then pointed at whoever hadn’t gone silent as she bid you bonjour with eyes scanning for someone doing something that would make them that day’s target. All done with a mischievous smile.
