English is:
1. my hobby - it's a pleasure to watch a film, to read a book, to listen to a song, to recite a poem...
2. my job - I'm paid for doing different things in English (see above )
3. a very useful tool - to surf the net, to read manuals, to get various information, to communicate with people of different cultures and what not
4. another way of thinking (compared with my mother tongue and other languages): there are issues that are more convenient to think about in English
5. an amusing brain-training exercise - I find much more animation in English grammar drills than in crossword puzzles
6. the last but not the least - a perfect way of hiding disappointment or irritation (e.g. when I get annoyed with smb I start speaking English as if by mistake and it gives me time to pull myself together)
all in all, I'd say, English is my lifestyle, I can hardly imagine my life without it.
