Why learning new languages is amazing?

It makes you feel near to new cultures and new people. In addition, you have more chances to get a job than people who don't talk as many languages as you. And of course, your brain improves because of the process of learning. It's not necessary to be a genius to learn a new language, and it's interesting and exciting. So why not?

In my opinion, the way of life in any country is determined by the culture of people living there. Once the cultures significantly differed from each other around the world. However, due to the emergence of the communicative devices, such as phone, TV, satellite and so on, the cultures, and as a result this new way of life, have gotten closer to each other. Clearly my country, (which country??), is not an exception too. The Plenty of things has been changed over the time, but what is now in my mind is the change in women's lifestyles. In the past, they usually stayed at home and did housework, like raising children, cooking, washing dishes and so on. In return the men were responsible for supplying  providing for the whole family financially. Consequently, they spent most of their time out of the house, working to get enough income to supply support their family. But nowadays both men and women work outside of the home and do housework together. To me, this is a good stuff. But One of the negative changes in the modern lifestyle, according to me, is too little physical movements in the daily life, because it leads to many kinds of decrease damages the human body, both physically and mentally.

Why am I here?

I have to learn English. If not, then my mom will go crazy (and nobody wants that) and my dad would start his: "You are going to be nothing if you don´t learn another language". So I decided to start improving my English. As you can read I am not the best writer, and in the CAE the teacher said I was a disaster in speaking and writing. So here I am. I hope you can understand what I am trying to communicate. If it´s helpless, please tell me so I can change the language. Maybe Portuguese.
I am poor so I can´t have a teacher, because I can´t pay; however I´ll do my best. So, thanks for your corrections. I hope you can help me.
Basically, I´m going to comment about my daily life. And it´s more interesting that it seems. I almost forgot, I am Peruvian. And... I think that is all. I am looking forward to read my mistakes.
