How to learn English fluently?

It is one of members' experience in learning English:

The english we studied was quite poor and stuffed with boring grammar rules. At the end of my studying course I wasn't even able to deal with simple things in english, not to mention understanding natives. About 2 years ago I decided I wanted to learn english and became good at it!! I didn't attend a school because my job doesn't get me the chance to schedule a fixed time. I can be free for a week and then all of a sudden I have to work for 20 hours continuosly. So, I've been studing almost only through the internet. For this reason I think I have many things to share with you. This blog reflects my point of view on the subject and perhaps some teachers and educationists won't agree completely with me. This is only my own experience, I'm not an expert and since every person is different, take my advise with a pinch of salt. I think what I've done is working for me because in a 2 years time I achieved a quite satisfactory level. Now I can convey in english confidently and fluently. I still make many mistakes but I see them as an apportunity to correct and improve. And then, you know what? Once you deal with english every day, It starts being like a drug!! You get addicted! So now, I can't help staying with my everyday english as much as I can.
