I think the one thing that I will regret once I'm settled in Seattle is that I did not learn to speak Korean, or at least not well.
I tried self studying. I tried to take a class. I tried to learn through my Korean friends and acquaintances. I bought a book, a phrase book, a CD. Unfortunately, however, I just never found the time to sit down and practice.
Three years later, I'm leaving Korea with just my survival phrases, words, and numbers that I've learned and used repeatedly. Maybe one day I'll revisit Korea and I'll actually have the time to study and speak the language.
