Something about me

I'm an optimistic girl who comes from Chinese China.Now I am a college student and (I) have been studying English for 8 years, I like it.There is always an I have a dream, that one day I can communicate with others fluently in in fluent English so that I can get to know more about the world and find out more happyiness things which belong to the world. I love laughing, we always say,"Laugh ten years less,Smile ten young ." And I believe that if we keep being happy,then all everything that is around us will be better. So just smile, regardless of what you face,all everything will be okay.

I corrected "I have a dream" just because it sounds more natural; about the sentence "Laugh ten years less,Smile ten young" I actually don't know what you meant, so I can't correct it.
Good luck with your studies! :)
