The only question was when.Millennials are already one of the most charitable generations in history. In one year, three of four US millennials made a donation and seven out of ten raised money for charity.But it’s not just about money. You can also give time. I promise you, if you take an hour or two a week — that’s all it takes to give someone a hand, to help them reach their potential.Maybe you think that’s too much time. I used to. When Priscilla graduated from Harvard she became a teacher, and before she’d do education work with me, she told me I needed to teach a class. I plained: “Well, I’m kind of busy. I’m running this pany.” But she insisted, so I taught a middle school program on entrepreneurship at the local Boys and Girls Club.I taught them lessons on product development and marketing, and they taught me what it’s like feeling targeted for your race and having a family member in prison. I shared stories from my time in school, and they shared their hope of one day going to college too. For five years now, I’ve been having dinner with those kids every month. One of them threw me and Priscilla our first baby shower. And next year they’re going to college. Every one of them. First in their families.We can all make time to give someone a hand. Let’s give everyone the freedom to pursue their purpose — not only because it’s the right thing to do, but because when more people can turn their dreams into something great, we’re all better for it.Purpose doesn’t only e from work. The third way we can create a sense of purpose for everyone is by building munity. And when our generation says “everyone”, we mean everyone in the world.Quick show of hands: how many of you are from another country? Now, how many of you are friends with one of these folks? Now we’re talking. We have grown up connected.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 enpasses the entire world.We understand the great arc of human history bends towards people ing 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 ing together not just as cities or nations, but also as a global munity.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 munity 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 munities right now.We all get meaning from our munities. Whether our munities are houses or sports teams, churches or music groups, they give us that sense we are part of something bigger, that we are not al
