Always practice whenever you can, watch English shows, read lots of articles and books

I think it would be beneficial to have some English-speaking friends who are willing to help you. As I'm trying to learn Spanish, sometimes I'll send text messages in Spanish. At times I find myself thinking in very basic Spanish phrases-- so I believe that to mean I'm progressing :) You can also change your facebook and phone settings to English.

The quickest way to learn is immersion and actually speaking. Tv also helps :)
