This is true even of people we think of as prodigies. Mozart, for example, famously started writing music at six. But, writes the psychologist Michael Howe in his book
Genius Explained,

by the standards of mature composers, Mozart’s early works are not outstanding. The earliest pieces were all probably written down by his father, and perhaps improved in the process. Many of Wolfgang’s childhood compositions, such as the first seven of his concertos for piano and orchestra, are largely arrangements of works by other composers. Of those concertos that only contain music original to Mozart, the earliest that is now regarded as a masterwork (No. 9, K. 271) was not composed until he was twenty-one: by that time Mozart had already been composing concertos for ten years.

The music critic Harold Schonberg goes further: Mozart, he argues, actually “developed late,” since he didn’t produce his greatest work until he had been composing for more than twenty years.

To become a chess grandmaster also seems to take about ten years. (Only the legendary Bobby Fischer got to that elite level in less than that amount of time: it took him nine years.) And what’s ten years? Well, it’s roughly how long it takes to put in ten thousand hours of hard practice. Ten thousand hours is the magic number of greatness.

Here is the explanation for what was so puzzling about the rosters of the Czech and Canadian national sports teams. There was practically no one on those teams born after September 1, which doesn’t seem to make any sense. You’d think that there should be a fair number of Czech hockey or soccer prodigies born late in the year who are
so
talented that they eventually make their way into the top tier as young adults, despite their birth dates.

But to Ericsson and those who argue against the primacy of talent, that isn’t surprising at all. That late-born prodigy doesn’t get chosen for the all-star team as an eight-year-old because he’s too small. So he doesn’t get the extra practice. And without that extra practice, he has no chance at hitting ten thousand hours by the time the professional hockey teams start looking for players. And without ten thousand hours under his belt, there is no way he can ever master the skills necessary to play at the top level. Even Mozart—the greatest musical prodigy of all time—couldn’t hit his stride until he had his ten thousand hours in. Practice isn’t the thing you do once you’re good. It’s the thing you do that makes you good.

The other interesting thing about that ten thousand hours, of course, is that ten thousand hours is an
enormous
amount of time. It’s all but impossible to reach that number all by yourself by the time you’re a young adult. You have to have parents who encourage and support you. You can’t be poor, because if you have to hold down a part-time job on the side to help make ends meet, there won’t be time left in the day to practice enough. In fact, most people can reach that number only if they get into some kind of special program—like a hockey all-star squad—or if they get some kind of extraordinary opportunity that gives them a chance to put in those hours.

So, back to Bill Joy. It’s 1971. He’s tall and gawky and sixteen years old. He’s the math whiz, the kind of student that schools like MIT and Caltech and the University of Waterloo attract by the hundreds. “When Bill was a little kid, he wanted to know everything about everything way before he should’ve even known he wanted to know,” his father, William, says. “We answered him when we could. And when we couldn’t, we would just give him a book.” When it came time to apply to college, Joy got a perfect score on the math portion of the Scholastic Aptitude Test. “It wasn’t particularly hard,” he says matter-of-factly. “There was plenty of time to check it twice.”

He has talent by the truckload. But that’s not the only consideration. It never is. The key to his development is that he stumbled across that nondescript building on Beal Avenue.

In the early 1970s, when Joy was learning about programming, computers were the size of rooms. A single machine (which might have less power and memory than your microwave now has) could cost upwards of a million dollars—and that’s in 1970s dollars. Computers were rare. If you found one, if was hard to get access to it; if you managed to get access, renting time on it cost a fortune.

What’s more, programming itself was extraordinarily tedious. This was the era when computer programs were created using cardboard punch cards. Each line of code was imprinted on the card using a keypunch machine. A complex program might include hundreds, if not thousands, of these cards in tall stacks. Once a program was ready, you walked over to whatever mainframe computer you had access to and gave the stack of cards to an operator. Since computers could handle only one task at a time, the operator made an appointment for your program, and depending on how many people were ahead of you in line, you might not get your cards back for a few hours or even a day. And if you made even a single error—even a typographical error—in your program, you had to take the cards back, track down the error, and begin the whole process again.

Under those circumstances, it was exceedingly difficult for anyone to become a programming expert. Certainly becoming an expert by your early twenties was all but impossible. When you can “program” for only a few minutes out of every hour you spend in the computer room, how can you ever get in ten thousand hours of practice? “Programming with cards,” one computer scientist from that era remembers, “did not teach you programming. It taught you patience and proofreading.”

It wasn’t until the mid-1960s that a solution to the programming problem emerged. Computers were finally powerful enough that they could handle more than one “appointment” at once. If the computer’s operating system was rewritten, computer scientists realized, the machine’s time could be shared; the computer could be trained to handle hundreds of tasks at the same time. That, in turn, meant that programmers didn’t have to physically hand their stacks of computer cards to the operator anymore. Dozens of terminals could be built, all linked to the main-frame by a telephone line, and everyone could be working—online—all at once.

Here is how one history of the period describes the advent of time-sharing:

This was not just a revolution. It was a revelation. Forget the operator, the card decks, the wait. With time-sharing, you could sit at your Teletype, bang in a couple of commands, and get an answer then and there. Time-sharing was interactive: A program could ask for a response, wait for you to type it in, act on it while you waited, and show you the result, all in “real time.”

This is where Michigan came in, because Michigan was one of the first universities in the world to switch over to time-sharing. By 1967, a prototype of the system was up and running. By the early 1970s, Michigan had enough computing power that a hundred people could be programming simultaneously in the Computer Center. “In the late sixties, early seventies, I don’t think there was anyplace else that was exactly like Michigan,” Mike Alexander, one of the pioneers of Michigan’s computing system, said. “Maybe MIT. Maybe Carnegie Mellon. Maybe Dartmouth. I don’t think there were any others.”

This was the opportunity that greeted Bill Joy when he arrived on the Ann Arbor campus in the fall of 1971. He hadn’t chosen Michigan because of its computers. He had never done anything with computers in high school. He was interested in math and engineering. But when the programming bug hit him in his freshman year, he found himself—by the happiest of accidents—in one of the few places in the world where a seventeen-year-old could program all he wanted.

“Do you know what the difference is between the computing cards and time-sharing?” Joy says. “It’s the difference between playing chess by mail and speed chess.” Programming wasn’t an exercise in frustration anymore. It was
fun
.

“I lived in the north campus, and the Computer Center was in the north campus,” Joy went on. “How much time did I spend there? Oh, a phenomenal amount of time. It was open twenty-four hours. I would stay there all night, and just walk home in the morning. In an average week in those years, I was spending more time in the Computer Center than on my classes. All of us down there had this recurring nightmare of forgetting to show up for class at all, of not even realizing we were enrolled.

“The challenge was that they gave all the students an account with a fixed amount of money, so your time would run out. When you signed on, you would put in how long you wanted to spend on the computer. They gave you, like, an hour of time. That’s all you’d get. But someone figured out that if you put in ‘time equals’ and then a letter, like
t
equals
k,
they wouldn’t charge you,” he said, laughing at the memory. “It was a bug in the software. You could put in
t
equals
k
and sit there forever.”

Just look at the stream of opportunities that came Bill Joy’s way. Because he happened to go to a farsighted school like the University of Michigan, he was able to practice on a time-sharing system instead of with punch cards; because the Michigan system happened to have a bug in it, he could program all he wanted; because the university was willing to spend the money to keep the Computer Center open twenty-four hours, he could stay up all night; and because he was able to put in so many hours, by the time he happened to be presented with the opportunity to rewrite UNIX, he was up to the task. Bill Joy was brilliant. He wanted to learn. That was a big part of it. But before he could become an expert, someone had to give him the opportunity to learn
how
to be an expert.

“At Michigan, I was probably programming eight or ten hours a day,” he went on. “By the time I was at Berkeley I was doing it day and night. I had a terminal at home. I’d stay up until two or three o’clock in the morning, watching old movies and programming. Sometimes I’d fall asleep at the keyboard”—he mimed his head falling on the keyboard—“and you know how the key repeats until the end, and it starts to go beep, beep, beep? After that happens three times, you have to go to bed. I was still relatively incompetent even when I got to Berkeley. I was proficient by my second year there. That’s when I wrote programs that are still in use today, thirty years later.” He paused for a moment to do the math in his head—which for someone like Bill Joy doesn’t take very long. Michigan in 1971. Programming in earnest by sophomore year. Add in the summers, then the days and nights in his first year at Berkeley. “So, so maybe...ten thousand hours?” he said, finally. “That’s about right.”

Is the ten-thousand-hour rule a general rule of success? If we scratch below the surface of every great achiever, do we always find the equivalent of the Michigan Computer Center or the hockey all-star team—some sort of special opportunity for practice?

Let’s test the idea with two examples, and for the sake of simplicity, let’s make them as familiar as possible: the Beatles, one of the most famous rock bands ever; and Bill Gates, one of the world’s richest men.

The Beatles—John Lennon, Paul McCartney, George Harrison, and Ringo Starr—came to the United States in February of 1964, starting the so-called British Invasion of the American music scene and putting out a string of hit records that transformed the face of popular music.

The first interesting thing about the Beatles for our purposes is how long they had already been together by the time they reached the United States. Lennon and McCartney first started playing together in 1957, seven years prior to landing in America. (Incidentally, the time that elapsed between their founding and their arguably greatest artistic achievements—
Sgt. Pepper’s Lonely Hearts Club Band
and
The Beatles
[White Album]—is ten years.) And if you look even more closely at those long years of preparation, you’ll find an experience that, in the context of hockey players and Bill Joy and world-class violinists, sounds awfully familiar. In 1960, while they were still just a struggling high school rock band, they were invited to play in Hamburg, Germany.

“Hamburg in those days did not have rock-and-roll music clubs. It had strip clubs,” says Philip Norman, who wrote the Beatles biography
Shout!
“There was one particular club owner called Bruno, who was originally a fairground showman. He had the idea of bringing in rock groups to play in various clubs. They had this formula. It was a huge nonstop show, hour after hour, with a lot of people lurching in and the other lot lurching out. And the bands would play all the time to catch the passing traffic. In an American red-light district, they would call it nonstop striptease.

“Many of the bands that played in Hamburg were from Liverpool,” Norman went on. “It was an accident. Bruno went to London to look for bands. But he happened to meet an entrepreneur from Liverpool in Soho who was down in London by pure chance. And he arranged to send some bands over. That’s how the connection was established. And eventually the Beatles made a connection not just with Bruno but with other club owners as well. They kept going back because they got a lot of alcohol and a lot of sex.”

And what was so special about Hamburg? It wasn’t that it paid well. It didn’t. Or that the acoustics were fantastic. They weren’t. Or that the audiences were savvy and appreciative. They were anything but. It was the sheer amount of time the band was forced to play.

Here is John Lennon, in an interview after the Beatles disbanded, talking about the band’s performances at a Hamburg strip club called the Indra:

We got better and got more confidence. We couldn’t help it with all the experience playing all night long. It was handy them being foreign. We had to try even harder, put our heart and soul into it, to get ourselves over.

In Liverpool, we’d only ever done one-hour sessions, and we just used to do our best numbers, the same ones, at every one. In Hamburg, we had to play for eight hours, so we really had to find a new way of playing.

Eight hours?

Here is Pete Best, the Beatles’ drummer at the time: “Once the news got out about that we were making a show, the club started packing them in. We played seven nights a week. At first we played almost nonstop till twelve-thirty, when it closed, but as we got better the crowds stayed till two most mornings.”
