Hey, of course there is no career without English, but on the other hand not everyone has to know or use it everyday. I mean, it looks nice in your CV but what does a simple plumber or carpenter need it for? The chances of using it are really small on regular basis..
As far as I am concerned, I decided to take up second studies and starting from the new academic year I'll be studying Latin+Greek+Italian, adding to English which I study now, and to German, Spanish and Gaelic I've been learning for some time for my own satisfaction. I don't feel I will be using these languages every day, but I just have too much free time:p Now, seriously, it's my passion (probably except for German - I've been learning for like 5 years and know nothing, although I strongly desire to pass successfully ZMP next year) :)
Now, I know many people who spend their holidays somewhere in GB although they know squat about the language and culture. They would insist that they can do without knowledge of a language, because they work mainly either with other people of similar level of English or alone. After some time there (e.g. a month) they seem to have forgotten what they had come there for and are quite happy. What did they come to England? To brush up their language..but even after 3 months spent in this way, they still cannot communicate without using their hands..
To Kachna: I have just started learning Latin (on my own) and I found it so similar to Spanish and so .. original that I feel I just love it despite the fact that many many people are trying to discourage me from learning. But while learning Latin I get to know so much about ancient times and modern languages (obviously I am talking about languages based on Latin) that I am glad that I decided to study it simultaneously with English:)
