Why I need to learn English.

I work in the academic world, especially in topics related to the electrical engineering. In this field, the language that is used principally is the English. The best information that can be found regarding electrical engineering/my job is written in the English language. Spoken English is also frequently used in activities such as conferences, symposia, and anything related to verbal communication. I need to learn English because I'm meddled in this world, but also because it is a language that is spoken in a lot of countries as a second language. Knowing English would help me in case I ever have the chance to travel. I think that learning English will give me the opportunity to communicate with English speakers more easily.
