（产品设计）的过程才是最奇妙的地方。

    当初我们开始做（Mac电脑）时也是这样，我们曾经有很多绝妙的想法。但我一直感觉，如果一个团队是在做他们真正看好的事情，过程就像……就像我小时候。当时我住的那条街上有一位鳏居的老人。他80多了，长相有点吓人。我对他稍微有些了解。我想他可能曾经付钱让我给他割草坪或其他什么的。

    有一天，他对我说：“到我的车库去看看吧，我想给你看些东西。”他拖出了一个布满灰尘的旧磨石机。它由一个马达、一个咖啡罐以及一个连接的传动带构成。然后，他说：“跟我来。”我们走到了后面，捡了些石子。就是那种普普通通、粗糙难看的石子。我们把石子放进那个罐子，再倒进一些液体和一点点磨石粉，然后把罐子盖好。他开动了马达，然后对我说：“我们明天再来看看。”

    石子在罐子里转动，罐子铛铛直响。

    第二天我回到那里。我们打开罐子，取出来的是一些非常光滑的石子。普通石子放进罐子里通过这样（他拍手）相互摩擦，有一些小摩擦，有一点噪音，出来时就是这样光滑的石子。

    在我的脑海里，这个过程与一个团队在努力地做他们热爱的事情是一样的。团队这群才华横溢的人们相互碰撞，相互争论，有时甚至是争执。这个过程中可能会有一些噪音，但是大家通过共同的努力，相互打磨，而团队的想法也得到打磨，最后出来的就是这些真正光滑、漂亮的石头。

    这部70分钟的影片定于周三和周四（11月16日和17日）在美国19个城市的Landmark Theaters院线上映。点击这里了解放映时间表和预售票情况。

    And it's that process that is the magic.

    And so we had a lot of great ideas when we started [the Mac]. But what I've always felt that a team of people doing something they really believe in is like is like when I was a young kid there was a widowed man that lived up the street. He was in his eighties. He was a little scary looking. And I got to know him a little bit. I think he may have paid me to mow his lawn or something.

    And one day he said to me, "come on into my garage I want to show you something." And he pulled out this dusty old rock tumbler. It was a motor and a coffee can and a little band between them. And he said, "come on with me." We went out into the back and we got just some rocks. Some regular old ugly rocks. And we put them in the can with a little bit of liquid and little bit of grit powder, and we closed the can up and he turned this motor on and he said, "come back tomorrow."

    And this can was making a racket as the stones went around.

    And I came back the next day, and we opened the can. And we took out these amazingly beautiful polished rocks. The same common stones that had gone in, through rubbing against each other like this (clapping his hands), creating a little bit of friction, creating a little bit of noise, had come out these beautiful polished rocks.

    That's always been in my mind my metaphor for a team working really hard on something they're passionate about. It's that through the team, through that group of incredibly talented people bumping up against each other, having arguments, having fights sometimes, making some noise, and working together they polish each other and they polish the ideas, and what comes out are these really beautiful stones.
