Long before the Kardashians made millions of dollars, thanks to their reality show and fame, Kourtney Kardashian got some money advice from her late father. She may have people helping her with her finances now, but the advice she got from her father is the one thing that she keenly follows.

In an interview with CNBC at the Create & Cultivate conference in San Francisco, Kourtney revealed what her late father Robert Kardashian told her about money. “The biggest thing that my dad always told us was just that money doesn’t buy happiness,” she said.

Robert didn’t just share the idea of money not buying happiness as a nugget of wisdom. He made sure that his children followed it by drilling it into them.

It was important for Kourtney to pass on her experience with this advice at the Create & Cultivate conference because the event was aimed at building the next generation female entrepreneurs. The topics that were discussed at the event include the importance of financial literacy and ideas about how to raise capital.

Kourtney may not be as successful as some of her other sisters, Kylie Jenner leads the list with a billionaire tag, but she still boasts of a $35 million net worth. She is also a big social media influencer with close to 82 million followers on Instagram.

Apart from her late father, Kourtney also learnt a lot from her boyfriend in college, who apparently taught her everything about credit. She bought her first car with this new knowledge.

Kourtney’s advice to the women at the conference was to not be afraid to try new things. She also told the entrepreneurs there that it is always better to negotiate personally to get the best possible deal, instead of having someone else negotiate.

The company that Kourtney has founded is Poosh, a lifestyle and health focused venture. The reality TV star and business woman uses her massive following on Instagram to promote the products of her company.
