There are absolutely lots of teachers who are trying to come into the profession, but they are not attracted enough to say, 'I'm going to switch careers to do it,' or they are often not retained... because the salaries and the compensation aren't there to make it happen.
Sometimes it would be nice to just have some red wine with dinner, but it's not worth the risk. I have a great life, a great situation. Why would I want to risk self-destructive behaviour?
