Learning another language is not something really easy to do, it takes plenty of time and discipline to success on it because is not just talking, it requires a lot more of work, you have to understand and completely change in a lot of senses, not literally but you will think with other words so the things that you say or the way that you express perhaps will not be the same that you would say on your mother tongue, so in someway your personality change a little and that's something hard to do, for me personally it seemed to be something impossible to do.
The English classes are really enjoyable for me, now these days, with the sacrifice of time and energy that the university has, I don't have the chance to explore my "creativity" and writing is something that I don't do too often but I think we all should do, express ourselves is a good way to relieve the amount of stress that we carry on our shoulders.
