Your audience is out there, you simply haven’t found them yet.
You can have the best message and/or product out there, but without an audience, you will have nothing.
Outline who your audience is, write down what they are looking for and what they need from you, then craft your message, the one that will help them understand who you are and what you are about.
It might not work the first time, but that’s the idea, to keep iterating until you do find them, and then your message will become crystal clear as to why you never did this before.
