First of all, travelling abroad is a great idea in order to improve the knowledge of languages which is right now a vehicle to move from one country to another looking for a job.
In addition, it helps you to set a lot of relationships with people of foreign countries. Living abroad makes you more tolerant because you need to adapt your habits to other cultures, trying to respect them as you would want yourself to be.
To sum up, studying abroad makes you more mature and it´s also a great experience that you will remember your whole life.
