What does it mean to be a professional communicator?
When you're communicating with your people, your message should be well orchestrated and clear. You have to make sure that you know the words that you're using and it should not confuse your people.
Keri on the other hand has a tendency to speak in colloquialisms and she loves using sports metaphors, especially those involving baseball.
She realized later on that she has people from multiple countries that don't know American baseball and have no idea what she's talking about. So anytime she finds herself using a sports metaphor, she would stop and define it so her people could understand her.
Do not assume that everybody else knows what you know.
Another piece of advice is you have to take inventory of all the people you are communicating with. You have to be thoughtful with who you are communicating with, not just what you are communicating about. Avoid involving people that are not supposed to be involved in your agenda.
If in any case, you make a mistake about this, it's okay.
It happens. It always does. As long as you are working with people and with yourselves, you'll make mistakes. It is part of human nature. People mess up especially in leadership, but it's okay.
As leaders, you are not your mistakes. Instead, you learn from them and improve by them.
