To become a good voice actor, Cartwright had to learn to become a good listener. She doesn't listen to what people say, as much as how they say things. I used to read stories to my children using them as guinea pigs to try out new voices. I don't get a lot of people coming up to me but, when it does happen, it brings such joy to people that I actually enjoy talking to them. Especially little kids - it freaks them out when I start talking like Bart.

This is the best job on the planet. We work so little, we get paid a lot of money. I'm doing what I love to do. It's my whole purpose in life. We only get together about once a week.
