Do you feel AWKWARD with your hands in a conversation?
If you're not the main speaker in a conversation, it's fine to put your hands by your side!
If you are the main speaker, it's important to learn some basic hand gestures when you speak.
But if you still feel a bit awkward, I always like to hold something, like a drink. This makes me feel a lot more relaxed and reduces the pressure of overthinking what to do with my hands.
