I hope I don ' t sound like a dick , but if you aren ' t sure what to put on a demo , you are not ready to start working . I hope I ' m wrong , and I hope you book everything , but without a basic understanding of the business , you may be in for a big waste of time . Find some classes even online . Find a coach even online . Do a play not online . Best of luck ! <| sep |> yeah , it ' s annoying as hell . I know I ' m a big guy and I ' m workin on it . <| sep |> That ' s not how money works . The unit they ' re normalized to is effectively arbitrary . <| sep |> Good points . Thanks for being civil . And thanks for clearing up my lack of understanding about dB . <| sep |> That ' s not a number provided by them my dad did the math . and it ' s a close family friend running the company .
