In our society, we often don't do big things because we're so afraid of making mistakes that we ignore all the things wrong today if we do nothing. The reality is, anything we do will have issues in the future. But that can't keep us from starting.

在我们的社会里，我们并不经常做一些伟大的事，因为我们害怕犯错。如果我们什么都不做，我们就忽视了今天所有的错误。事实上，我们所做的任何事情将来都会有问题。但这不能阻止我们开始。

So what are we waiting for? It's time for our generation-defining public works.

那我们还在等什么呢？ 现在轮到我们这一代人定义“公共事务”的时候了。

How about stopping climate change before we destroy the planet and getting millions of people involved manufacturing and installing solar panels? How about curing all diseases and asking volunteers to track their health data and share their genomes? Today we spend 50x more treating people who are sick than we spend finding cures so people don’t get sick in the first place. That makes no sense. We can fix this. How about modernizing democracy so everyone can vote online, and personalizing education so everyone can learn?

在地球摧毁之前，如何阻止气候变化？如何让数百万人愿意参与制造和安装太阳能电池板？ 如何治愈所有疾病？如何要求志愿者跟踪他们的健康数据和分享他们的基因组？ 今天，我们可能要花上50倍的价格去治疗病人，而不是找到一种治疗方法让人类第一时间无法染上疾病。这并不合理，我们可以解决这个问题。 民主现代化如何让每个人都能在网上投票，以及通过个性化教育让每个人都能学习？

These achievements are within our reach. Let's do them all in a way that gives everyone in our society a role. Let's do big things, not only to create progress, but to create purpose.

这些成就在我们能力范围内是可以实现的，让我们让每个人在我们社会中发挥其应有的作用来做这些事情。让我们做一些伟大的事情，不仅要创造进步，而是要创造purpose。

So taking on big meaningful projects is the first thing we can do to create a world where everyone has a sense of purpose.

所以我们可以做的第一件事就是，创造一个每人都拥有使命感的世界。

The second is redefining equality to give everyone the freedom they need to pursue purpose.

第二件事是，重新定义平等，让每个人都有追求目的的自由。

Many of our parents had stable jobs throughout their careers. Now we're all entrepreneurial, whether we're starting projects or finding or role. And that's great. Our culture of entrepreneurship is how we create so much progress.

我们这一代人的父母，很多在整个职业生涯中都有稳定的工作。但是现在，我们这一代人都是企业家，无论我们是刚开始一些项目还是在寻找、或是已经扮演着这个角色。这都很棒，我们的创业文化恰好是导致我们创造如此多进步的原因。

Now, an entrepreneurial culture thrives when it's easy to try lots of new ideas. Facebook wasn't the first thing I built. I also built games, chat systems, study tools and music players. I'm not alone. JK Rowling got rejected 12 times before publishing Harry Potter. Even Beyonce had to make hundreds of songs to get Halo. The greatest successes come from having the freedom to fail.

现在，只要在尝试很多新想法的时候，创业文化就会蓬勃发展。 Facebook并不是我做的第一件事，我还做过游戏、聊天系统、学习工具和音乐播放器。我并不孤独， 因为JK罗琳在出版《哈利波特》之前被拒绝了12次，即使碧昂丝也不得不写了数百首歌曲，才有了今天Halo这首歌获得的光环。最大的成功来自于我们享有失败的自由。

But today, we have a level of wealth inequality that hurts everyone. When you don't have the freedom to take your idea and turn it into a historic enterprise, we all lose. Right now our society is way over-indexed on rewarding success and we don't do nearly enough to make it easy for everyone to take lots of shots.

然而，今天，财富不均会让每个人都受到伤害。当你没有自由把你的想法变成一个历史性的企业的时候，我们就输了。现在，我们的社会在通往成功的路上有过多的指引，但我们做的不够，并不是每个人都能够轻易得分（获得成功）。

Let's face it. There is something wrong with our system when I can leave here and make billions of dollars in 10 years while millions of students can't afford to pay off their loans, let alone start a business.

面对现实吧，我们的社会体系是有问题的，当我能够离开哈佛并在10年内赚取数十亿美元的时候，还有数百万学生无法偿还贷款，更不用说开始创业。

Look, I know a lot of entrepreneurs, and I don't know a single person who gave up on starting a business because they might not make enough money. But I know lots of people who haven't pursued dreams because they didn't have a cushion to fall back on if they failed.

看，我认识很多企业家，然而我并不知道是否有一个人是因为没有足够的钱而放弃创业。但是我知道很多人不敢追求梦想，因为一旦他们失败，并没有很好的缓冲（承托住）。

想要成功，幸运是很重要的因素

We all know we don't succeed just by having a good idea or working hard. We succeed by being lucky too. If I had to support my family growing up instead of having time to code, if I didn't know I'd be fine if Facebook didn't work out, I wouldn't be standing here today. If we're honest, we all know how much luck we've had.
