I started my VO career five years ago and there are times when it can be very frustrating. Avi's podcast helped me get through some of those moments where I felt like giving up. I'm not claiming that it's an inspirational-themed podcast or anything, but hearing from some of our VO peers talk about their journey was very encouraging.
There does not seem to be any new content springing up anymore but Avi's podcast is definitely worth a listen. His recording quality is great. His guests are top notch voice actors that I guarantee you've heard before. Avi himself seems to put the guests at ease and draw out fun, meaningful, and useful conversations. I use Pat Fraley's mini spray bottle technique to this day and I've never heard that trick from anywhere else.
Give this podcast a try. My favorite is the Holiday Special and Rochard Horvitz. Good stuff!
