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.

Figure out WHY you're doing what you're doing and remind yourself of it constantly. Every day, every hour. Hold onto that for dear life. But don't expect anyone else to necessarily believe you, or know what is in your heart.

You can't believe your own hype, or your own worst moments. Neither is as important as knowing your "why." The harder the challenges are, the more this matters. It is a true gift that I'm so grateful for to my core when someone else sees and acknowledges my why. But you can't expect it or need it. Your ability to really see yourself can power you through.

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.

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!

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.

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.
