It's physically hard for me to work. I start to break down, physically. My joints start. I get weepy eyes. I don't sleep well. I was never a hard worker, I guess. So the voiceover work ethic is really great for me - couple days a month, two hours a day.
I started doing comedy with no plan to do voice work. Voice work came as a function of doing comedy and meeting people who eventually develop shows like that. I didn't seek out from an early age to be on cartoons.
I've learned to wait 'til an idea is worth making. That's not really a lesson I've learned; I sort of always did it that way. But there's no reason or need to make videos prior to when you make a show, because then you need material for it.
