It so happened in my life that I've been learning Russian since the age of 5. So even if I'm not a bilingual in the full sense of the word I absorbed the feeling of beauty of the language, of the cultural phenomemenae related to the country of the language learned and musical styles and movements in particular. The more you learn about the culture the more appreciated and close it becomes to you whereever you are. But if you are outside the environment of the language you learn and the speech doesn't surround you it's hard to know everything that's born in the language every day, e.g., slang expressions, abbreviations etc. And if you are a learner you often feel uncomfortable, unnatural, untrue every time expressing your emotions by means of the intonations which differ from ones in your native language. That's the reason why learners shift back to habitual intonations and start producing a bad accent. The conclusion is you shoud practice as much as possible until hardships fade away, until you get used to what seems strange. So if you really adore some activity you'll never think how many lessons a week you need to attend to gain the skill you want. Only self-commitment is sutable to make your dreams come true.
