So this is 11-year-old Marley Dias, and she is an editor-in-residence at Elle magazine. Yep, you read that correctly.
Marley was invited to create her own online publication, Marley's Mag, for Elle.com after running the hugely successful book drive #1000BlackGirlBooks.
The aim of the campaign, which launched in November 2015, was to collect and donate 1,000 books in which black girls are the main characters.
Marley said this was "important because when you are young you want to read lots of books, but you especially like to read books with people that look like you".
In her mission to "create this space where black girls' stories are read and celebrated in schools and libraries", the schoolgirl collected more than 7,000 books.
It led to Marley being interviewed on The Ellen Show and meeting with Oprah Winfrey and Michelle Obama.
"I've always said that books have taken me on many adventures, but none of those adventures have been quite like this one," Marley wrote in her first editor's letter. "This isn't a dystopian novel or a fantasy. It's my real life. I, Marley Emerson Dias, have gotten the chance of a lifetime. I'm creating a brand-new zine for one of the most-read magazines in the world."
Here's 11-year-old Mikaila Ulmer, the CEO and founder of Me & the Bees, who recently signed an $11 million deal with Whole Foods.
Combining her great-grandmother's recipe for flaxseed lemonade and her love of bees, Mikaila started her own company.
After learning about what bees do for the ecosystem and their rapid decline, Mikaila wanted to do something to help save the world’s honeybee population. A percentage of the profits from the sale of her lemonade goes to organisations who support this cause.
Mikaila was also featured as a celebrity chef at the 2016 Easter Egg Roll at the White House.
Mars, 16, and Sage Adams, 19, are the talents behind the Art Hoe Collective.

The collective is popular among young celebrities including Willow Smith and Amandla Stenberg.

Alongside her clothing line, Ify is an anti-bullying activist and a junior ambassador of peace. She uses her love for fashion to raise awareness of bullying.
Sisters Kayla Davis, 19, and Keonna Davis, 21, are making waves with their company KD Haircare.
