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."
