As a voiceover professional, your product is intensely personal.
It’s your own voice. It’s how you communicate with others.
If you’re not in voiceover try recording yourself and listening. Did you cringe? Would you send that recording to someone and ask them to hire you?
Voiceover amplifies self-doubt: you wonder if you should just stop talking if no one hires you.
But then something happens. You get hired. You get used to the sound of your own voice because you play it back so often. You begin to understand that acting matters more than the pleasant sound of your voice, and that you get hired because you're relatable.
