Albert Einstein broke up his day by returning home from his Princeton office at 1:30 p.m., having lunch, taking a nap, and then waking with a cup of tea to start the afternoon. Thomas Edison napped for up to three hours per day. Winston Churchill considered his late afternoon nap non-negotiable. John F. Kennedy ate his lunch in bed before drawing the curtains for a one- to two-hour nap. Others who swore by daily naps include Leonardo Da Vinci (up to a dozen 10-minute naps a day), Napoleon Bonaparte (before battles), Ronald Reagan (every afternoon), Lyndon B. Johnson (30 minutes a day), John D. Rockefeller (every day after lunch), Margaret Thatcher (one hour a day), Arnold Schwarzenegger (every afternoon), and Bill Clinton (15–60 minutes a day).
Ben Franklin once wisely said: “An investment in knowledge pays the best interest.” Perhaps the source of Buffett’s true wealth is not just the compounding of his money, but the compounding of his knowledge, which has allowed him to make better decisions. Or as billionaire entrepreneur, investor, and philanthropist Paul Tudor Jones has eloquently said, “Intellectual capital will always trump financial capital.”
