It's great to know that you find the English Language interesting.
Honestly, when I was still a student, I didn't dream of becoming an English teacher. My dream then was to become a science teacher or a nurse. However, I had this very good professor in college who encouraged me to study English as my specialization.
From then thereon, I started studying the English language. Bereft of English teachers who were well - versed on the subject, I had to learn the language on my own. My only recourse was our library's old and dilapidated books. During my time the internet wasn't that too popular in our place. ☺
