It’s time for our generation-defining public works. 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?
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.
So taking on big meaningful projects is the first thing we can do to create a world where everyone has a sense of purpose.

So what are we waiting for?

Now it’s our turn to do great things. I know, you’re probably thinking: I don’t know how to build a dam, or get a million people involved in anything.
But let me tell you a secret: no one does when they begin. Ideas don’t come out fully formed. They only become clear as you work on them. You just have to get started.
If I had to understand everything about connecting people before I began, I never would have started Facebook.

It’s good to be idealistic. But be prepared to be misunderstood. Anyone working on a big vision will get called crazy, even if you end up right. Anyone working on a complex problem will get blamed for not fully understanding the challenge, even though it’s impossible to know everything upfront. Anyone taking initiative will get criticized for moving too fast, because there’s always someone who wants to slow you down.
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.

Every generation has its defining works. More than 300,000 people worked to put a man on the moon – including that janitor. Millions of volunteers immunized children around the world against polio. Millions of more people built the Hoover dam and other great projects.
These projects didn’t just provide purpose for the people doing those jobs, they gave our whole country a sense of pride that we could do great things.
