Lisa Rinna recently delighted "Days of Our Lives" fans when she returned to reprise her role as Billie Reed on the spin-off "Beyond Salem." Of course, Rinna has fond memories of her time on the original soap and even reveals what she learned from her daytime television gig (via Today). 

"I really appreciate that training that I got 30 years ago because once you do a soap opera, you can pretty much do anything," she said. The actress added that working on the soap "prepared [her] to be professional," which she says involves always being on time, sufficiently memorizing her lines, and putting in a full day's work. 

"You show for work, you don't even call in sick," Rinna said. "I would have to be on my deathbed to not show up for work. Like, that is just ingrained in you when you're working as an actor on a soap opera."

She also shared that she took the lessons she learned from "Days of Our Lives" and applied them to her career on reality TV shows such as "The Real Housewives of Beverly Hills."
