Being a teacher AND realising a dream (in my case writing a novel)

Firstly, let me get something clear, I love teaching. When you've thoroughly planned a lesson, it's going well and the students are on board, there's nothing better. This is not a post (the sort you sometimes see) by people jaded with the profession about a "plan B" or "getting out while you still can". This is about being able to do something you really want to, as well as be a great teacher.
