"You carry yourself well" What does that even mean?

"Carrying yourself well" Seems rather ambiguous but it's really just the physical manifestation of inner confidence; Head held high, looking people in the eyes, speaking clearly, and smiling brightly. Quite honestly, your body language impacts how people view you much more than what you say.

Perhaps in your next interaction, you should worry less about what you’re saying and take time to consider how you present yourself.
