That F-word—finance—can be pretty intimidating sometimes.

But one professor out of the University of Chicago claims to have all the answers you’ll need to know—and it apparently can all fit on a single index card.

Prof. @HaroldPollack will answer your personal finance questions on #Reddit tomorrow from 10 AM to 12 PM CST! #AMA pic.twitter.com/3OnyCFrdnT — UChicago (@UChicago) January 21, 2016

Author and professor Harold Pollack just released a new book, The Index Card: Why Personal Finance Doesn’t Have to be Complicated (co-written by Helaine Olen), which claims to detail just 10 rules to mastering your funds.

Pollack recently hosted an Ask Me Anything (AMA) session on Reddit, tackling all those not-so-fun things you have to think about now that you’re an adult (boooooo): student loans, 401ks, how to save towards purchasing your first house, and more.

Check out a sampling of some of Pollack’s most interesting—and surprising—bits of advice.
