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!

Women in business, women in employment anywhere face a very different set of challenges than their male counterparts.

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.

In my safe corporate job, I might have made one decision of real significance a year. As an entrepreneur, it feels like I'm making a decision every minute - I have lots of balls in the air, and so yes, sometimes I drop one or two. And for the most part, the balls are made of rubber and they bounce. So instead of carrying one ball very carefully, being worried that I might not be holding it at exactly the right angle, I am juggling hundreds, and I have to remind myself to appreciate all the balls I keep up in the air for every one that gets dropped.

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.
