You need to know what to say first, what to hit home with, what to let linger. You need to prioritize.
This demands that you say No to many aspects of your product that you may love. So it goes. You can talk about it all you want once you have their attention. Then they're all ears, or at least some of them are. But if you try to speak really quickly to get it all in, to try and say it all at once, it's going to come out gobbledygook.
To brand is to prioritize.
