In July 2023 Astrid Buffett was overheard complaining about the price of a $4 cup of coffee, arguing she “could get a pound of coffee” for the same price elsewhere. What is striking is that she complained at a “summer camp for billionaires” and she is married to Warren Buffett.

We’re all familiar with the wisdom, success and longevity of this billionaire investor. Yet when probed about his most important decision, Buffett ignores investing and money – he says it’s all about who you marry. “Marry the right person. I’m serious about that. It will make more difference in your life. It will change your aspirations, all kinds of things.”
