In Issue 2 of Becoming Berkshire, Warren Buffett heads from college life at the University of Pennsylvania to Nebraska, nearly takes a full-time job at JCPenney, gets rejected by Harvard, and then finds the teacher who changes everything: Benjamin Graham.

This episode covers Buffett’s years from 1947 to 1951, his arrival at Columbia, the lessons he learned from Graham, and the three core ideas that became the foundation of his investing life: owning pieces of businesses, using a margin of safety, and treating Mr. Market as your servant, not your master.
