And don't try to bring the audience to where you are. Especially when you don't have an audience yet.
And when you can't get a hold of your potential audience where they usually hang out, when they still don't listen to you even though you're spreading your message where they are, well then your idea, message or whatever might simply suck.
And you might have to spend some more time and work a bit more on fine tuning your message, your idea, or your product. And try to make sure that where you assume your audience hangs out is really the place where they hang out.
It only works this way. It only works when you are where your audience is. It doesn't work the other way round. Never...
