Learning a language
Learning a languaje sometimes is difficul for people, there is the pronuntiation, there is the grammar, and the most important the vocabulary I think. People study languages for work, for their future and for their own interest. Truly any language is really important but worldwide the most important at the time are English, Chinese, German, and the Spanish. When you go to another country for travel and your a tourist, always someone knows your language and if is not the case you always know a little of language where you are travelling.
Finally, I think that at the time the lenguages are the most important for people who wants travel or work abroad.
