When trying to convince someone of something, use the following format:
Tell them what you’re going to tell them.
Tell them.
Tell them what you just told them.
In other words, audiences learn from repitition. In Spanish they say “con sangre, entra la letra,” or “learning comes in with blood,” meaning that you have to beat the lesson into people.
So the literal beating doesn’t work these days but you can still hit them with your endlessly repeated message.
