One turn of phrase around telling people something over and over is to say you “repeated ad nauseam”, or literally until you were sick.
One of the simplest to address gaps I see in leaders around engaging their people is to assume they have communicated their message enough.
If in any doubt, you absolutely haven’t told them often enough.
I simplify the latin linked phrase for them to:
“When you are sick to death of communicating your message…
… you are probably halfway there.”
If in doubt, tell them, tell them again, tell them some more.
Put another way, repetition, repetition, repetition.
As professional speakers often advise:
In the opening, you tell them what you are going to tell them.
In the body, you tell them.
In the conclusion, you tell them what you’ve told them.
Or, one more time:
“When you are sick to death of communicating your message…
… you are probably halfway there.”
Do I need to tell you again ?
