Why do I want to learn English? I think it is [the] last technical barrier to [establishing] global citizenship. Even though I could not get a job in California [a few years ago] as I [had wished], one of my top priorities in Seoul [remains] learning this language, [so that I can speak English with the] people I meet, and [understand] various viewpoints on a world [in which] I live. Overall good job! I didn't understand what you wanted to say in the last sentence, so I guessed and filled in the blanks!
