introduce myself

nice to meet you. my name is dongwon from korea.
im 24years old. i am university student. my major is business.
i have been here for 4months. nevertheless, my english doesnt look like better.
not only havent i improved my english, but also my english is getting worse.
i dont know reason.
just sick and tired of ny life, and no more interesting no more exciting.
but i cannot stop study english. because english can show my ability to other peaple.
and ability is connected with good salary and happy life in korea.
in my opinion, it's unfair. because we dont use english after enter the company even though it is very important to judge his ability.
anyway, im so nervous. do i go to right way? is it correct?
always i ask by myself.

i know. there is no solution except studying hard.
always i remind a proverb in my mind.
"no pain no gain"
it's reasonable, and i firmly believe that.
i hope that everything's gonna be fine.
