What does a teacher do? And what’s the best way to learn a language?

A teacher is in charge of guiding and motivating the student as possible, because the material is already there and it will always be there. But us a teachers we have to tell them from where to start and how to go. Motivation does not depend the 100 percent on the teacher, its half student and half teacher because they are a complement.

To learn a language you need to have a goal, a motivation and a good teacher (or you can be your own teacher by following like a pathway but still you will need someone to guide; by telling you how to pronunciate word, to explain you grammatic better etc.) but the best ways is being constantly and perseverant.
