Gloria Steinem says she has no regrets about not having children and wants to live well into her 100s

• Gloria Steinem, 90, is the first guest on Bobbi Brown's new YouTube series, "I Am Me."
• In Thursday's episode, the 90-year-old activist discussed aging and her choice to skip motherhood.
• Brown told Business Insider that she aims to uplift and inspire women with this video series.

Gloria Steinem wouldn't mind being one of the oldest women in the world.

The writer and activist, 90, recently sat down with Bobbi Brown to appear as the first guest on the beauty legend's new YouTube series "I Am Me," which launched Thursday.

During their discussion, Steinem reflected on her life in the public eye, the evolution of women's empowerment, and her feelings about skipping motherhood and aging.

Regarding the latter topics, the author said she's satisfied in both areas.

When Brown asked Steinem who would carry her legacy, the activist replied, "lots and lots and lots of people" — from modern artists she admires to parents.

Steinem said single mothers, especially, inspire her. She believes a "huge" factor in her success over the years is that she was never responsible for raising children — giving her time to focus solely on herself and her work.

"Any regrets on that?" Brown asked.

"No, no, absolutely not," Steinem said. "I'm not sure why except perhaps because when I was growing up, I was looking after my mother, who was not well. I've noticed that other people who were small people looking after big people don't want to do it again."

She also said she would "maybe" describe herself as a big sister of the women's empowerment movement but would never assign herself the title of its mom.

"I've never been a mother," she said.

On the topic of aging, Steinem said she's comfortable with herself in her ninth decade and is excited to get older.

"I'm 90 years old. Hello?" Steinem said to Brown. "I looked up to find the oldest woman in the world, and I found a woman who's 130, supposedly — so I have a goal."

The activist also said that not working from an office daily spares her "the compulsion" to regularly look in the mirror. When she does, however, she's not surprised or bothered by what she sees.

"I don't care about getting old, except I love it here, and I don't want to leave," Steinem said.

In an email to Business Insider, Brown said that helping women love themselves has always been a core part of her career — from launching her first namesake makeup line to her current beauty venture, Jones Road.

With this series, she wants to take that effort further and show that "success doesn't come easily."

"We all face challenges, no matter how perfect things look on the outside," Brown said. "The message is simple: the best thing you can do is to be yourself."

And she's learning that lesson herself from each guest on her show.

"We all have our struggles and battles with self-doubt," Brown said. "The key is how we rise above the challenges and choose to move forward with vision and confidence. I've learned to look at obstacles as opportunities — and every one of the inspirational women on 'I Am Me' has their own stories of how they got there."
