English! I don't know a second language, but I took Spanish 101 at a community college for fun while at my office job. And I'd like to get fluent one day. (I have a fantasy about retiring in Spain after visiting Barcelona and loving it.)
I don't know to be honest! I think I would get bored of any one place. So I think it would being able to have the freedom to do whatever I want regardless of money. Like travel the world or stay at home when I get sick of travel. XD Spending that time with friends and family. <3
