Facebook's COO spoke to Barnard College in 2011 about the importance of women feeling empowered in the workforce, and gave some foreshadowing to her future book, Lean In:
"I hope that you — yes, you — each and every one of you have the ambition to run the world, because this world needs you to run it. Women all around the world are counting on you. I’m counting on you. I know that's a big challenge and responsibility, a really daunting task, but you can do it. You can do it if you lean in. So go home tonight and ask yourselves, 'What would I do if I weren't afraid?' And then go do it."
