First notebook entry: Introducing myself

Hello friends there. im MH from South korea. (Hello there friends, I'm MH from South Korea.)
and iI'm here to find some friends, and to improve my eng through this website.
Introducing myself.. actually its not easy for me to introduce myself even in my mother tongue (native language) korean. but i think its the first step of this and then so i need to do it. i live in seoul, korea, my job is computer related things such as developing computer programs .
i enjoy hiking knaps around my place, swimming ( particularly skin diving, snorkeling,. i ve I've been to overseas to enjoy diving, )
anyways.. i hope i can make some friends here.
thanks

Nice Job "I" isalways capatalized in more formal writing.  Also with contractons (I'd, isn't, aren't, can't, doesn't etc...) don't forget the apostrophe.
