James Altucher recently posted about the smartest piece of financial advice he'd ever received:
"Everyone has to be smarter than me for me to get involved."
The whole post is a great story of ups and downs that's all about having a beginner's mind at all times.
Read the post, then watch Jeremy Irons perform this very idea below. In this scene, from the movie Margin Call, he's the CEO of a large investment bank on the brink of the housing collapse a decade ago. In my career I've dealt with many high-level executives in banking and other industries. The best of them approach meetings exactly like this (even with very small problems).
