Be careful not to sneak too many glances at your watch, especially if you are in a conversation with a colleague.
Watching the clock implies impatience and can be considered disrespectful.
In most startup businesses, the culture has become more relaxed over time. However, that doesn’t mean you can express your ideas with exaggerated gestures.
Wild hand motions could indicate that you’re unprofessional and don’t have a lot of confidence. Instead, keep this type of nonverbal behaviour to a minimum, unless it involves happy hour drinks with a few friends.
If your body isn’t facing the conversation, you run the risk of seeming disengaged (or even rude).
Take a moment and square your shoulders and torso towards the group. If you’re sitting down, turn the chair to face the action.
