I can't, I have to get the doctoral degree to get there. I am still learning, and have a long way to get through. English as a field of study is not as easy as you think it is. You should be able to scrutinize every single word, phrase, clause, sentence and paragraph you write, speak, listen and read to identify yourself as an English teacher. It seems, I thought mistakenly, if I master English grammar, I will master English Language as a whole. So, it was on account of building vocabulary and their usage properly in forming sentences. But, it turned out that grammar is just used to boost your learning of a language. Therefore, I am trying to make that up by reading daily newspapers and Writing. I hate teaching children, so I will not teach at public schools. What I am looking for is enhancing my English language skills and get the required experience to move on into the next stage which would be completing my study.
