Her best advice? She quotes the oft-cited "’Find a job that you love, and you'll never work a day in your life.’ And then I think stick-to-it-iveness and tenacity. … I talk about doing the "Tonight Show" with Johnny Carson, but that happened after auditioning 22 times."

The comedian has one other important piece of advice for anyone trying to make it in show biz: Always tip the waitstaff. "I've been around long enough that I've actually run into women who've made it as performers and commented that they waited on me and I was a nice tipper," Carol says, remembering a run-in with Kate Flannery from "The Office," who waited on Carol years before Flannery’s TV debut.

Carol also reflected on her time as a writer on "Seinfeld."

"What was great about working there was Larry David and Jerry really wanted female ideas because it rounded out the show," she explains. "I worked with a lot of evolved guys who had their eyes and ears open."
