Let's have an honest conversation about what's going on. A man and a man at a bar looks like mentoring. A man and a woman at a bar looks like dating.

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.

The traditional metaphor for careers is a ladder, but I no longer think that metaphor holds. It just doesn’t make sense in a less hierarchical world... Build your skills, not your resume. Evaluate what you can do, not the title they’re going to give you. Do real work. Take a sales quota, a line role, an ops job. Don’t plan too much, and don’t expect a direct climb. If I had mapped out my career when I was sitting where you are, I would have missed my career.
