There's a difference between being intensely focused and being mindlessly redundant. Intelligent people may worry they won't appear knowledgeable unless displaying the full range of their minds. Such people often have a hard time disciplining themselves to repeat any message again and again. It isn't half as interesting to repeat yourself as it is to trade fresh thoughts and ideas. But that's beside the point.
Repetition is one of the big guns of effective message campaigns.
Audiences understand why it's done. The frequency of a consistent message is crucial to winning the competition for mindshare in an environment with 80,000 other message points that are drawing attention at the same time. Pushing a message forward into public awareness usually means pushing it uphill, and it requires a lot of steps. Keep doing it. Stay on point.
