I was obsessed with looking rich and overspent in my 20s. Then one HR meeting exposed how little I knew about money.

Dow Jones.

When she got a dream job at age 25, she didn't have basic adult money skills or investing knowledge.

The moment she stopped avoiding her finances and took control, her whole life shifted.

In this book excerpt from "Future Rich Person," author Haley Sacks , creator of Mrs.

Dow Jones , shares how an embarrassing 401(k) conversation sparked her money journey.

Back in my 20s, I wanted to be a comedian.

I was working as a page at Late Show with David Letterman during the day and doing stand-up and improv on the Lower East Side at night.

In my free time, I made YouTube videos you will never find (don't even try it) like "GRWM to Zip Zap Zop." On the side, I babysat a kid named Winthrop on the Upper East Side (yes, his real name), and this little Napoleon let me work on my internet videos if I let him watch wrestling instead of doing his homework. (Oh, and I also worked the front desk at a chic SoHo Pilates studio that Karlie Kloss and the Olsen twins favored, and no, I didn't have to sign an NDA, so ask me anything.) I was hustling like this for years until, at 25, I finally got my big break (a warning to readers who might not like name-dropping: I'm about to name-drop): Lorne Michaels, the man who started "Saturday Night Live," was hiring for two creative social residents.

I got the job alongside Ben Marshall (who you may know now as the redhead from "SNL").

Dream job territory.

I went in there full of hope, giving Leslie Knope energy.
