I am not there yet, but if I get there:
I teach and enjoy what I do. Would the SE be likely to prevent my doing that?
I have this image of suddenly breaking down in tears in front of the class, or being irritable and nasty to my students.
Is this LIKELY??
I would hate to retire due solely to the enjoyment factor, but if I had to retire the regrets would be tempered by the fact that 've had a good long career!
