Sheryl Sandberg, Facebook COO, delivered the keynote address at Barnard College’s commencement in May; her speech was inspiring and powerful. What she said will forever resonate with me, as young women of the 21st Century, we have a duty to close the ambition gap – that is what will spur true social change. Enough talking about the glass ceiling – break it!

“So today, we turn to you. You are the promise for a more equal world. You are our hope. I truly believe that only when we get real equality in our governments, in our businesses, in our companies and our universities, will we start to solve this generation’s central moral problem, which is gender equality. We need women at all levels, including the top, to change the dynamic, reshape the conversation, to make sure women’s voices are heard and heeded, not overlooked and ignored. So my hope for all of you here, for every single one of you, is that you’re going to walk across the stage and get your diploma. You’re going to go out tonight or maybe all summer and celebrate. You deserve it. And then you’re going to lean way into your career. You’re going to find something you love doing, and you’re going to do it with gusto. You’re going to pick your field and you’re going to ride it all the way to the top. So, what advice can I give you to help you achieve this goal? The first thing is I encourage you to think big. Studies show very clearly that in our country, in the college-educated part of the population, men are more ambitious than women. They’re more ambitious the day they graduate from college; they remain more ambitious every step along their career path. We will never close the achievement gap until we close the ambition gap. But if all young women start to lean in, we can close the ambition gap right here, right now, if every single one of you leans in. Leadership belongs to those who take it. Leadership starts with you.”
