There’s a lot of ways to describe Kim Kardashian: socialite, reality TV star, sister, social media guru. But one label we can’t forget to ascribe to the mother of North, Saint, and Chicago? Businesswoman — and a badass one at that.

Love her or hate her, there’s no denying Kim Kardashian has built herself an empire. Whether it’s Keeping Up with the Kardashians, her cosmetics company KKW Beauty, or the Kim Kardashian: Hollywood app, Kardashian is one hardworking mama. In a recent post for Wealthsimple’s “Money Diaries” series, the famous entrepreneur opened up about learning to balance a checkbook, her spending and saving habits, and the best investment she’s ever made. Her best investment probably isn’t what you think, but it IS one that you can make right now, for free.

“Is it cheesy to just say the best investment I’ve made is I’ve invested in myself and believed in myself?” Kardashian writes. (No, Kim. Not at all.) “I’ve always had that insane drive. Like if I want something bad enough, I always figure it out. Before I used to be just like, Oh it’s luck. But I have this drive inside of me where I’m just like, okay, this is the vision that I see for us and for the family, and let’s make it happen. I mean, I always want to win, and I’ve always been like that like from the start.”

Kardashian says she often turns to her mom, Kris Jenner, for advice.

Kardashian also wrote about her very first job.

She also learned important money lessons from her late father, Robert Kardashian.

Kardashian is a mogul worth millions now, but she’s been supporting herself from a young age.
