Well I'm impressed. Reading your profile made me forget I was on a foreign site :p. you seem like a talented young lady for being able to teach yourself. I tried teaching myself Chinese but after 6 months I still call people horse, and could not pronounce anything. I think I decided that language isn't my talent :p, but I won't give up! Eventually I'll get it.
You mention you work as an architect and interior designer, that is quite rare to hear! Interesting. How did you end up doing that?
