For any of us in this room today, let's start out by admitting we're lucky. We don't live in the world our mothers lived in, our grandmothers lived in, where career choices for women were so limited.

When it comes time to settle down, find someone who wants an equal partner. Someone who thinks women should be smart, opinionated, and ambitious.

Until women are as ambitious as men, they're not gong to achieve as much as men.

It is the ultimate luxury to combine passion and contribution. It's also a very clear path to happiness.

Two things that I think matter are gratitude and joy.

I hope you find true meaning, contentment, and passion in your life. I hope you navigate the difficult times and come out with greater strength and resolve. I hope you find whatever balance you seek with your eyes wide open. And I hope that you - yes, you - have the ambition to lean in to your career and run the world. Because the world needs you to change it.

My hope in writing 'Lean In: Women, Work, and the Will to Lead' was to change the conversation from what women can't do to what we can.
