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.

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!

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.

The most important part of my mental self-care is knowing who to call for what kinds of help.

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.

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.
