They gave me 18 experiments to complete in my 10 days in the ISS. That's a lot. Everyone told me I didn't have to complete all of them, that it wasn't expected of me. But I knew everyone was watching me, so I gave up meals and sleep and completed all 18 experiments. It's a very Korean thing to do.

If you ask me what's harder, being famous or flying to space, I'd say fame is much harder.

Only in space did I realize how lucky I am to be Korean. Only in Korea could I have gone to space before turning 30 years old.
