Rumer Willis does not take this year for granted. In fact, the last 12 months have been the most memorable of her life, thanks, in large part, to her sisters Scout, 23, and Tallulah, 21.

"Both of them are probably the two most inspirational people," Willis told her "Dancing With the Stars" partner Val Chmerkovskiy, according to PEOPLE. "Literally, they could not care less what anybody thinks of them."

The girls, Rumer included, have dealt with media criticism for much of their lives, but that doesn't seem to faze them.

Without fear, Tallulah recently opened up about having an eating disorder and other issues, saying the Scout actually "forced" her to acknowledge that there was a problem.

"I can say that I'm getting to that place where I'm starting to feel okay with myself, bit by bit," Tallulah told Teen Vogue.

As Rumer's sisters continue to inspire her, she too is doing some inspiring of her own on "DWTS."

"I've had the most personal growth I've ever had this year," she said. "People are so ready to jump on anything you do and have an opinion on it."
