J Just like finding your voice didn’t happen overnight, most likely, neither will finding your audience. This is where faith comes in; you just have to know that they are out there. In cases like this, evidence comes after the fact. You have to proceed forward before wherever you’re trying to get to can come into focus. No one’s foresight is that good. People who insist on having evidence beforehand, typically only move backwards because they already know what’s behind them.
A lack of evidence doesn’t mean moving towards something blindly either. There is so much variety in the human experience that it pretty much makes it a statistical certainty that there is an audience out there for everything. Before you put faith in anything or anyone else, first invest it in yourself.
