Here you will find suggestion about your question. Interesting!

Watching English movies and television is how some of my friends have learned English.

The best way to be fluent in English is a work and Travel program, you spend at least three months working in the Disney for example and when you return your English will be great. Just need to be wary, many people fall on a trap with fake jobs and may become slaves abroad. Or even you can do high school in an English language country, but to live with a native family involves a risk, not all people are friendly.

Thank you very much for your comments!
I think travel is the best way to learn a language and working abroad is the best solution.

Now, I just need to understand how can I improve my English using a weblog.

Hope to find out.

Find English speaking friends and keep talking to them, observe how they use the language and just talk and talk, practicing the language.

Using the youtube, I guess it is a good source with hundreds of new videos playing everyday.
