To the leader who objects to communicating a thing on the grounds that, "I said that last month."
When you remember the lessons your parents taught you, you say, "My mother always said. My father always said."
It's not just what you say. It's what you always say. (And also what you never say, but that's another story.)
Lean on your communication staff to help you find new ways to say it and new illustrations of its truth.
But don't say don't want to say it because you've already said it.
Because if it is important, you must always say it.
As you always tell your kids.
