It's not just language skills that people do a year abroad for - important as they are - it's much more for the soft skills which are so much in demand both by companies and by people themselves, to grow as a person as I mentioned.
The self reliance, broader outlook, confidence in one's own abilities, ability to get on with very different people etc. are all qualities which will stand you in good stead for life.
When employers etc, are picking out people they want, as opposed to people who could do the job, a year abroad ( if you can point to those qualities you have acquired ) is one of the pointers they are searching for. It will suggest to them that you have learned things that other people may not have, that you have personal qualities that are rare, that you have leadership potential because of the character it has helped you to develop.
As I said all these things are learned the hard way - by experiencing the culture shock not by joining the ex pats, by learning to live and cope alone not by getting a flat with 2 other Brits, by registering with the local police, by finding work, by creating your own new life by searching out new friends among the locals, immersing yourself in the new way of life. It is not easy. It can be very lonely and disorientating. But this is how you learn. There will be many occasions 2 months in when you think, stuff it I'm going home or I'm going to join that ex pat club then at least I'll have some ready made friends to chat with. And you will have admitted defeat not just to yourself but to everyone else too. Any employer interviewing you will suss you out immediately as some one who gives up when the going gets rough. You learn nothing by keeping in your nice safe little life.
The more you sort things out yourself , the more you will learn and the more valuable you will be to future employers and future friends and family and the stronger you will be as a person to face the inevitable 'slings and arrows of outrageous fortune.'
There is no such thing as an easy life - the best you can hope for is to give yourself as many opportunities as possible to learn the coping skills we all need. Maybe the year abroad during your course will be the only opportunity you will ever have to experience this sort of challenge. How many people do you know who would tremble at the thought of leaving family and friends to live in another British town where they know no one? Think what respect anyone who has made a life for themselves in a foreign country will command.
