"Apparently I'm a perfectionist, which I didn't know before," she told PEOPLE Friday at the Race to Erase MS Gala in L.A. "I guess I have some perfectionistic qualities when it comes to my own performance. I'm learning to lower my own expectations as far as having unrealistic expectations of myself."
But the former Full House star, whose partner is Mark Ballas, said that she's exceeded her own expectations about how far she'd make it in the competition.
"I'm thrilled to death to have made it through to week eight," she explained. "My personal goal was week six, so I am pumped! After next week is the semi-finals, so of course I would love to make it through to the end, but I'm kind of laughing, because if I do make it, I know that I'm the dark horse in the race."
The mom of three, who said her husband, former hockey player Valeri Bure, has helped her "a ton" with advice because he competed on a similar reality show in Canada, knows she has some tough competition to beat if she's going to get her hands on that glittering mirror-ball trophy.
"Meryl [Davis] is just killing it every single week, and she's just amazing to watch," the 38-year-old admitted.
So is she going to have to pull a Tonya Harding to beat her?
Cameron Bure burst into laughter, before saying, "Don't think I haven't thought about that!"
