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. Women all around the world are counting on you. So please ask yourself: What would I do if I weren't afraid? And then go do it.
