Rome wasn't built in a day; Practice makes perfect.
I've been learning English for ten years.Only God konws how much effect I put into it!As a reward,I'm dealing with foreign customers now.
The best way to learn English is keep practising everyday,learn it happily and freely.Never stick to your textbooks and ridiculous grammar for high scores.Read English newspapers,magazines,novels etc.to broaden your horizons; watch English movies to help you understand English culture.
*read,listen and write!
