Kendall Jenner is a model, a reality star, an Instagram sensation… and now a journalist as well.
In the February issue of Wall Street Journal Magazine, the 19-year old is dubbed one of six "luminaries” (along with Goldie Hawn and Tim Howard) to reflect on their time as a youth.
"I feel like I grew up too fast a long time ago," writes Jenner for the publication.
It is true that Kendall first appeared alongside half-sister Kim Kardashian and the rest of the family on Keeping Up with the Kardashians when she was only 11 years old.
Elsewhere, as she has throughout her impressive rise up the modeling industry, Kendall attributes her success to being a "workaholic," not to having a famous last name.
And she also says she's aware that life can go by pretty darn quickly.
"I just turned 19 a couple weeks ago, and I'm scared to be 20, it's the first step out of being a teenager," Jenner says, adding:
"My sister [Khloe Kardashian] always says to me and my younger sister, Kylie: You have your whole life to be an adult but only so long to be a kid. And we get it.
"In the right situations, I try to be as immature as I can sometimes - react to things as if I were 12. You can't take things too seriously."
No. But you can wear a shirt sometimes if you're trying to remain a child for as long as possible. Sheesh, Kendall!
