Have you given up? Are you at the point where you just don't see the point in doing anything differently, in learning anything more, in trying anything new? Have you been at it for a while? Are you comfortable with things the way they are? Are you planning to just keep on keeping on until you can retire?
Get out of the classroom!
This may sound harsh, but I think it needs to be said. Too many people are in the profession just hanging on until they age out of the system. Tenure protects them. Difficult procedures are in the way of getting them to leave by force. So just quit. Do all of us a favor and find something else to do with your time. Teaching is not a profession where you have the luxury of becoming complacent. Kids deserve better.
So, get back on your horse, or ride it into the sunset...now. Don't wait those last few years. Whose kids are you going to cheat out of a better education while you ride out the last few years on cruise control? Not mine.
