I have always considered interesting the way people learn languages, and working as a foreign language teacher, has helped me to discover important and curious things, about the way people acquire skills, in order to communicate in a different tongue.   

Speaking in other language, which of course, is not our native tongue, represents certain challenges, at the moment of teaching in class.  One of the most common challenges, in my personal opinion, is the use of first language, asked by students, to clarify something, they could not understand, in English language during the class. Should we completely prohibit the use of first language in class? Should I ask their questions again in English?  (When even I commit some mistakes speaking in English)  These and many other situations come to my mind, when I think about the challenges, of Speaking and working, in other language which is not my mother tongue. 

I have always heard, that easy things does not help you so much in life, and sometimes, difficult things help you to be a better person, and maybe, this is something we should apply in different contexts, in our lives.  One of the benefits to face any challenge is to prove ourselves that yes, we can handle it, and if we cannot, we must have enough engagement to be persistent,   in order to obtain our goals.

Refine or improve our English language level, will always be a positive aim, for any teacher of English as foreign language, and practice it abroad, in a native English speaker country, is an amazing experience that will be reflected when we return to our jobs in our country.
