Doing well with money isn't necessarily about what you know. It's about how you behave. And behavior is hard to teach, even to really smart people.

The field of finance, including investment, personal finance, and business decisions, is typically presented as a mathematical one, where we are given precise instructions based on data and formulas. However, people in the real world don't use spreadsheets to make important financial decisions. At the dinner table or in the conference room, people mix in their own backgrounds, perspectives, egos, prides, marketing strategies, and peculiar motivations to come up with these decisions.

To help you better understand one of life's most important themes, award-winning author Morgan Housel presents 19 short stories in his book The Psychology of Money.
