English is a truly powerful language. No matter what field you are studying or where you are from, it will help you take what you are doing to the next level. Language acquisition in its purest form is mostly about input. I, for instance, showed interest in the language at 8, and without any formal practice, started speaking fluently at about 13 years old. That methodology can be applied to any subsequent language you choose to study after you master English, and I will show you how.
