My best advice to working women is just try what you think right now will be best for you and your family - and if it doesn't work, then change it. And look for ways to cut corners to add to your sanity.

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.

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.

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.

Whether I'm traveling or at home in Seattle, my days rarely play out as it looks on my Outlook calendar - there's almost always something unexpected that comes up. But when I'm in town, my day usually starts at about 6 a.m., which is brutal for me because I'm really a night owl at heart.

Every day, possibly every hour as an entrepreneur, you do something that you absolutely could have done better with more time, more information, more experience, or more money - all luxuries you can't afford. So you do your best, and you move forward. The key is to see the forward momentum and not beat yourself up about how it could have been better.

My family immigrated from Korea when I was four years old, and when I started school, I didn't speak English. I remember that other kids would blame everything bad that happened in kindergarten on me - I spent a lot of time "in the corner" because I literally didn't have the words to explain that it wasn't me!
