My musical influences growing up were limited to Korean folk songs and hymns as I went to a Christian boarding school where I was not allowed to listen to secular music.

I learned to sing as I was learning to talk.

I grew up learning martial arts in Korea; my dad actually brought in an Olympic instructor to teach me as a teenager.

It's so astounding the amount of sacrifice the astronauts have to go through to do what they do and all the science involved in space exploration.

There's this constant guilt that comes with parenting. You always feel like you're never enough. If you're confident in your parenting, you probably suck at it.

I'm glad to say my father never felt ashamed of me, but my mother probably did.

To be honest, I'm a little upset these days. My family has been exposed to the media. Some people break into our house. My ex-girlfriend's photos are circulating online. To say that these are things I need to endure for the sake of celebrity... that's sad. I want to respectfully request that my private life remain private.

I love my 'Walking Dead' family. This is the best job I ever had.
