If people don't understand a thing you're saying, and you need them to understand, it's on you to figure out a different way to get through to them.
You need their beliefs to update, and if they don't understand, they won't.
If you just repeat the way it makes sense in your head, and it doesn't have an aha moment for them, you have to figure out a different way to unpack or frame it for them.
The vast vast majority of signal that is sent out in the world fails to be absorbed.
Because it assumes preexisting knowledge or motivation that doesn't match, or because it doesn't stand out in the cacophony.
The more nuanced and multi-layered and surprising the message, the less likely it's absorbed.
Finding succinct, compelling, clarifying utterances to deliver an insight is actually a large portion of having an insight that actually burrows into people's brains and changes their actions and thus produces impact in the world.
The original insight is easy.
Communicating it to others in a durable, efficient way is the hard part.
