The third way we can create a sense of purpose for everyone is by building community. And when our generation says “everyone”, we mean everyone in the world.

In a survey asking millennials around the world what defines our identity, the most popular answer wasn’t nationality, religion or ethnicity, it was “citizen of the world”. That’s a big deal.

Every generation expands the circle of people we consider “one of us”. For us, it now encompasses the entire world.

We understand the great arc of human history bends towards people coming together in ever greater numbers — from tribes to cities to nations — to achieve things we couldn’t on our own.

We get that our greatest opportunities are now global — we can be the generation that ends poverty, that ends disease. We get that our greatest challenges need global responses too — no country can fight climate change alone or prevent pandemics. Progress now requires coming together not just as cities or nations, but also as a global community.

But we live in an unstable time. There are people left behind by globalization across the world. It’s hard to care about people in other places if we don’t feel good about our lives here at home. There’s pressure to turn inwards.

This is the struggle of our time. The forces of freedom, openness and global community against the forces of authoritarianism, isolationism and nationalism. Forces for the flow of knowledge, trade and immigration against those who would slow them down. This is not a battle of nations, it’s a battle of ideas. There are people in every country for global connection and good people against it.

This isn’t going to be decided at the UN either. It’s going to happen at the local level, when enough of us feel a sense of purpose and stability in our own lives that we can open up and start caring about everyone. The best way to do that is to start building local communities right now.

We all get meaning from our communities. Whether our communities are houses or sports teams, churches or music groups, they give us that sense we are part of something bigger, that we are not alone; they give us the strength to expand our horizons.

That’s why it’s so striking that for decades, membership in all kinds of groups has declined as much as one-quarter. That’s a lot of people who now need to find purpose somewhere else.

But I know we can rebuild our communities and start new ones because many of you already are.
This is my story too. A student in a dorm room, connecting one community at a time, and keeping at it until one day we connect the whole world.

Change starts local. Even global changes start small — with people like us. In our generation, the struggle of whether we connect more, whether we achieve our biggest opportunities, comes down to this — your ability to build communities and create a world where every single person has a sense of purpose.

Class of 2017, you are graduating into a world that needs purpose. It’s up to you to create it.

Now, you may be thinking: can I really do this?

Remember when I told you about that class I taught at the Boys and Girls Club? One day after class I was talking to them about college, and one of my top students raised his hand and said he wasn’t sure he could go because he’s undocumented. He didn’t know if they’d let him in.

Last year I took him out to breakfast for his birthday. I wanted to get him a present, so I asked him and he started talking about students he saw struggling and said “You know, I’d really just like a book on social justice.”

I was blown away. Here’s a young guy who has every reason to be cynical. He didn’t know if the country he calls home — the only one he’s known — would deny him his dream of going to college. But he wasn’t feeling sorry for himself. He wasn’t even thinking of himself. He has a greater sense of purpose, and he’s going to bring people along with him.

It says something about our current situation that I can’t even say his name because I don’t want to put him at risk. But if a high school senior who doesn’t know what the future holds can do his part to move the world forward, then we owe it to the world to do our part too.

Congratulations, Class of ’17! Good luck out there.
