‘’John D. Rockefeller was one of the most successful businessmen of all time. He was also a recluse, spending most of his time by himself. He rarely spoke, deliberately making himself inaccessible and staying quiet when you caught his attention. A refinery worker who occasionally had Rockefeller’s ear once remarked: “He lets everybody else talk, while he sits back and says nothing.” When asked about his silence during meetings, Rockefeller often recited a poem: A wise old owl lived in an oak, The more he saw the less he spoke, The less he spoke, the more he heard, Why aren’t we all like that wise old bird? ‘’ -Morgan Housel Psychology of Money
