Ok let's just say you have zero experience in any kind of acting or the entertainment industry.
And you got you mic, DAW you signed up on fiverr. And you think I can sit back and wait and wait....Did I say wait. But while you are waiting for you first audition, what are you doing in the mean time. What's a Demo? Fell like your drowning. Here's the tip, think of it as being covered over by a Avalanche of information you didn't have a clue about. Don't panic look for clues. Drop your preconceived ideas and listen and do. And take on the problems one at a time. So when you get that audition, you might be nervous, but you know that you put your best foot (voice) forward.
