Kendall Jenner finally says what we've all been thinking.

The 19-year-old reality star-turned-model weighs in on the topic of youth in The Wall Street Journal segment "The Columnists," chatting about what it was like growing up on Keeping Up With the Kardashians.

"I feel like I grew up too fast a long time ago," she says. "Having older siblings, you grow up around adults, so you mature more quickly. I saw my sisters and parents working every day, so I was pretty much brought up to be a workaholic."

Kendall confesses that she's a little uneasy about leaving her teenage years behind. "But I just turned 19 a couple weeks ago, and I'm scared to be 20," she tells WSJ. "It's the first step out of being a teenager."

Big sis Khloe Kardashian is doing her part to ease Kendall's anxiety, offering up some sage advice. "My sister Khloe 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," she says. "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."
