How to learn a language very well?

Well, I can speak not badquite good English (You wouldn't normally say "I can verb not ..." because the negative sounds awkward. You could say "my English is not bad" though), but I still feel that there's a great lot of room for improvement.
Sometimes I think a language partner is very important, because he or she may affect how I speak.
If I meet the one in with a the similar level of proficiency, then it's fine. However, if I meet the one who's in the has a lower level of proficiency, then it'd probably hinder the quality and efficiency of communication.
Therefore, I hope I can meet someone who can speaks fluent English!

Good luck with the search!
