I think that for young people English is one of the most important things to learn. Personally I consider learning it the priority. My dream for future is to go to the USA and live there. I want to have chances for good job and earning much money. I know that I will need to know English perfectly. It is important to make no grammar mistakes and to know as much vocabulary as possible. At all job interviews, the person wanting to get a job is asked about his knowledge of English. When you know English well enough, you may look for a job as English teacher.
It is important to know English well, when you travel abroad. In most countries, people know at least a little English. I visited several European countries and I could speak English to all people there.
When you work with a computer, you have to know English. Most programs are written in this language. When you look for something in Internet or if you want to talk on-line to people, it is useful to be able to read and write in English.
If you plan to be rich, it is good to know English. You may go to England, Ireland or the USA and work there to become rich.
