Focus on what you know and what you control. The rest takes care of itself.
When I started performing as a Voice Talent in 2001 the world of VO was very different. All you needed was a good Agent. The audition process involved traveling to an office or studio. You'd sit in the greenroom with your pages - and you only had to perform - the Agency directed produced and submitted you.
For years I worked with and studied how the professional studios in downtown Chicago were set up. I observed what microphones I was put in front of, what pre-amps they used and most importantly their techniques and studio workflows. In 2015 I decided to heed the call and committed to pursue voice over work 100% which meant retiring my long running corporate career.
It's a bit more involved now then it was when I first started. That being said Voice over work isn’t really that different from any other "Buyer Seller" job. There's a product and I produce. And I strive to make that product quickly efficiently and to a high quality industry standard. That product is an Audition. I repeat that over and over and over again. Then I repeat that.
I love the Repeat part. The rest of it takes care of itself.
