Something about learning English

After wrote the title,I counted how many years of my English learning history.Well,I am shocked，it's 15 years until now!!!According to the law of 10000 hours,if I use on-third of the past 15 years in learning English,I would be an export.But I am not?
I started learning English when I was 10 years old as a junior student.As English is one of the 3 most important courses in China‘s ,it's closely related to entrance examination.Maybe because I had a little bit of talent in language learning，I did a good job in paper examination.Although I was wick in grammar and vocabulary. I couldn't speak out and was not interested in expanding because I learnt it just for exam.Then，after I entranced the college,I almost ignored English because My major was Japanese and then I worked in a japanese company.
Now ,I think I know the reason.The most important one is no driving force of myself.My aim was to get good scores in examination.So I had no interest in practicing my accent adn expanding my vocabulary.

It’s time to change.The most import reason make me change would be this:the world is so big,i want to know more by english.
