I've never been a teacher.
I have worked as a casting directing for 21 years and this career has provided me an ability in interacting with people and directing them.
For English, I spent 2 years in the US for my master degree. I confide that I can learn what to teach in a timely manner.
I am 50 years old, and I find it's a turing point in a career .. to do something rewarding to both myself and my country.
