English might not need a closer introduction, but I'll say a few words about it anyway. Nowadays, you simply can't get along without english.

Personally, I don't find english difficult at all. Unlike many other languages, you can practice English almost daily. English is all around. That can be practical since you need to learn it. I started learning it when I was about two years old. Actually, it was mom who was going to study, but I was the one who found it a lot of fun, so I was the one who learned the most.

English is spoken practically everywhere, by several billion people (at least as a second or a third language). As a first language it's spoken by about 300 million people. Wherever you go, you can probably get by with English.

I prefer to refer to the international version of English as Anglo. That's because I live in Northern Europe, and my friends in for instance Lithuania and India, hardly speak English. I mean, we don't live in England, and we're not from there. We don't speak American either, like the people of the USA, or Canadian, as they do in Canada, or aussie or oz (or whatever they call it in Australia) etc. Anglo. If you have a better suggestion, please let me know.
