When you talk your body express how you feel. Your words and tone of voice define your style and inclination.
But what about other mediums? Mail, chat, etc. Are you using your voice if the people you’re writing to are the same of a meeting?
You can be recognized, identifiable, with little tweaks and build meaningful connections only with some extra work.
Because if people like you when you talk, they’ll love you when you write, expressing those same traits that they are fond of.
