Legendary comedian Joan Rivers was just the second woman in U.S. history to helm her own late-night talk show. Before that opportunity arrived in 1986, she spent decades forging a path for future comics. In a 2012 interview with NPR’s “Fresh Air,” Rivers recalled her first break as a comedy writer: scripting dialogue for Topo Gigio, a mouse puppet slated to appear on “The Ed Sullivan Show.” While Topo Gigio’s 1961 debut could have been a one-off occurrence, Rivers’ words connected with the audience, and the puppet enjoyed an 11-year run on the series. During this time, Rivers became a familiar face on both “The Ed Sullivan Show” and “The Tonight Show Starring Johnny Carson.” By consistently recognizing and accepting challenges, she expanded her career into the realms of author and entrepreneur. Saying yes to opportunities is how you discover what you’re good at, and what you love.
