Do you think working abroad is essential for a successful career?

In mi opinion, working in a foreign country has some advantages. One of them is very important nowadays, I´m talking about learning languages. In fact, I think it already is essential these days to get a job, in the future,  to be able to speak a foreign language.
Specially in Spain it is important to learn other languages apart from Spanish and go abroad, because, at the moment, there are countries wich are more competitive than Spain regarding achieving success in your studies.
So, I think it´s esential to go abroad to succeed in your career, because you could acquiere new skills or qualifications.
