Bill Gates (and his successor at Microsoft, Ray Ozzie) are famous for taking annual reading vacations. During the year they deliberately cultivate a stack of reading material—much of it unrelated to their day-to-day focus at Microsoft—and then they take off for a week or two and do a deep dive into the words they’ve stockpiled. By compressing their intake into a matter of days, they give new ideas additional opportunities to network among themselves, for the simple reason that it’s easier to remember something that you read yesterday than it is to remember something you read six months ago.
