Elizabeth Olsen Lives by This Piece of Advice from Mary-Kate and Ashley: “‘No’ Is a Full Sentence”

Elizabeth Olsen may be best known to global audiences as Wanda Maximoff, the Scarlet Witch of the Marvel Cinematic Universe, but behind the blockbuster fame lies a woman guided by a simple, powerful mantra imparted by her famous older sisters: “‘No’ is a full sentence.”

The phrase, taught to her by Mary-Kate and Ashley Olsen, has become a cornerstone of Elizabeth’s career and personal philosophy—helping her navigate Hollywood on her own terms while protecting her mental health.

Wisdom from Her Sisters

Mary-Kate and Ashley, who rose to fame as child stars on Full House before stepping away from acting to build their fashion empire, passed along this lesson early in Elizabeth’s career.

In a 2022 interview with The Independent, Elizabeth recalled:

“When it comes to being a globally-recognized celebrity, I had two expert role models in my older sisters. They told me, ‘No is a full sentence,’ and that’s why I don’t hesitate to turn down anything I don’t want to do.”

The advice has proved invaluable, particularly when it comes to high-pressure Hollywood obligations. Elizabeth admitted she’s turned down presenting at awards shows after realizing the anxiety wasn’t worth it:

“I don’t like presenting at awards shows. I tried, and I don’t like it. It’s not worth the feeling of passing out that I get.”

Defining Her Own Path

While Elizabeth briefly appeared in her sisters’ projects as a child—including the 1994 TV movie How the West Was Fun—she stepped back, wary of becoming just “the Olsen sisters’ younger sibling.” Instead, she pursued her own education and training at NYU’s Tisch School of the Arts, making her breakthrough in the critically acclaimed Martha Marcy May Marlene (2011).

That independence carried into her Marvel career. Initially signing on for “a couple of movies,” she was surprised to see her role expand into the Emmy-nominated WandaVision (2021) and Doctor Strange in the Multiverse of Madness (2022). Throughout, she applied her sisters’ advice, choosing projects selectively and avoiding commitments that didn’t align with her goals.

A Sisterly Safety Net

Beyond career guidance, Elizabeth credits Mary-Kate and Ashley with providing a strong protective shield against the industry’s pressures. In a 2022 Harper’s Bazaar interview, she said:

“I felt very clear about how I was going to navigate lots of things because of watching them. I felt very protected.”

The support extended to practical recommendations about people to trust in the industry and, more broadly, the importance of keeping parts of life private. The twins—known for their minimalist fashion brand The Row and for their avoidance of social media—modeled a kind of authenticity Elizabeth has embraced in her own way.

She’s also open about the warmth behind their bond. Speaking in 2025 on Today with Jenna & Friends, she reflected,

“I loved being the baby. If I was spoiled by one, the other wanted to match it.”

A Lesson Beyond Hollywood

For Elizabeth, “‘No’ is a full sentence” is more than career advice—it’s a tool for life. She’s applied it to balance big-budget blockbusters with indie projects like Ingrid Goes West (2017) and His Three Daughters (2024). The principle has empowered her to prioritize both mental health and creative integrity.

As she told CinemaBlend in 2022, the phrase is “great wisdom not just for jobs, but everyday life.”

From her sisters, Elizabeth Olsen inherited not just a famous name, but a guiding principle that allows her to stand firmly in her own identity: saying no when it matters most, and knowing that no explanation is required.
