My first thought in moments of darkness and doubt is, "Who can I call? Who can I share this with?" Connection and sharing saves me every time.

As a woman leader, I try to take every opportunity I can to do what my mentors did for me - engaging with young women and take them seriously.

Most of my mentors and investors have been incredibly smart, thoughtful men. I've had the privilege of being mentored by some extraordinary men who saw something in me and took me more seriously than I knew how to take myself.

I've always had amazing women in my life help me with my kids. First it was my mom, and then a series of nannies and day care providers who were incredibly patient, kind, and loving. There is no blueprint - I think we all feel our way through it and just do the best we can, and it turns out that children are open to love from many different places and are pretty resilient, too.

The world is more flexible than you might think.

The thing that I've learned about taking risks is that the key question to ask is, "If this goes terribly, what will happen?" Usually, the answer is that the world won't come to a screeching halt. Usually you can go back. Maybe not to the exact same job, but usually to the same type of job.

When I think about work-life balance, I don't imagine it as a perfect day where I got to spend the exact right amount of time having an impact at work and snuggling with my kids at home. I never achieve that. But over the course of a month, or a quarter, or a year, I try to make time for the people and experiences I value.
