In the Shambhala Meditation Center, Tucson, Arizona, the practice is to read a passage from its teachings. Then there is a period of meditating. After that the passage is read again. It's only during the second time around that I get it.
A Baby Boomer, from the get-go I was trained in school to pay close attention to what was being said. Generations X, Y and Z weren't. Yet, my "monkey mind" still is off in a so many directions. The repetition of the content is downright necessary.
Thought leaders might hesitate to repeat. Perhaps you assume that will bore your readers and the audiences who attend your public speaking. Wrong. They would appreciate your ensuring they have access to the key points.
Only the trick is to frame the repetition so that it isn't experienced as mere reinforcement. That was the genius of John F. Kennedy. He found an infinite number of ways to repeat the message that he was leading a new generation.
