Random Walk on Wall Street is a great book on investing (spoiler alert: index funds).
I actually really found value in Tony Robins’ book on finance, even though it’s couched in a bit of an infomercial style. (And he advertises for some of his own companies, albeit transparently.)
You Need a Budget (the app / company) also made me think differently about budgeting. But, I still use the old version of their app and have no idea how well the new web-based version works in comparison.
I'd guess 50% or more I learned from my parents, 25%-ish from other school work ("advanced" math in secondary school, economics major at university), and 25%-ish from experience (huh, how did I run up this credit card? I shouldn't do that again!).
I had the impression that as an honors student, enrolled in primarily advanced classes from middle school onward, and then attending a top-20 university, it was just assumed I would know this stuff, or figure it out before getting into financial trouble. That was mostly true, though it's hard to comprehend how hard it can be to manage credit until you have a large credit line and a stable income.
If You Can: How Millennials Can Get Rich Slowly - William J. Bernstein
And all of the sources referenced in it. The Intelligent Investor by Benjamin Graham is also a good one.
Going through the material, I found I already knew 50-75% of it, but from bits and pieces of information I learned over the years, not one consolidated place. Is it the same for others?
