When asked about lifelong learning, Buffett lit up about reading. Someone in his family once described him as 'a book with legs,' and he wore the label proudly. To the common question of which famous person he'd most like to have lunch with, Buffett offered a characteristically practical answer: through books, you can have lunch with anyone who ever lived — and the lunch can last as long as you want. He urged graduates to maintain an inquisitive mind and never stop filling their heads with new ideas.
