Short is hard
Most people talk about their ideas in long form.
They want you to understand the logic of what it is.
And they summarize the impact with generic words like secure, efficient, or innovative.
They take a lot of presentation slides and walk you through the titles and bullets and graphics.
Show that it's solid.
And regardless of how much they try, they always feel that not enough has been said.
They're right. If they would speak for another three hours, they would still not answer the only questions that matter:
Why are you telling me this?
Why should I listen and care?
What is the cost of ignoring you?
If you answer just those three, you will get attention and people will engage.
