Student in English literature and theatre in the uk

I wish to become a teacher in the future for starters. I have had personal tutors in my childhood and know my way around it from a student's point of view. I want them to feel at ease as it isn't very encouraging to have to do personal work on one's language skills. And that I understand. I have lived in 9countries, which evidently helps me communicate easily with various different nationalities. Though, it mainly helps me understand why different nationalities struggle with certain words in English. It is easy to learn English from my point of view, but then again who am I to say; we are very different from one another and have very different backgrounds.
