Hey I'd love to read your blog, not that blogging does a writer make. But where is it?
Why do I equate writing ability with teaching ability? Because teaching writing skills is an integral part of teaching a well rounded EFL class. Granted, the majority of schools in China are looking for "Oral English Teachers," but even that requires a certain amount of writing.
And hey, don't take it so personally. I have no doubt that you are a very intelligent and maybe even wise person. However, I'm still not convinced you have the skills to make a real difference as a teacher. Hell, I'm sometimes not convinced I have the skills. I will say this though just to give you something to chew on: It is often more the little things that make a difference than it is the big things.
