if its too tough to handle, then leave the stresses of teaching for the well paid and cushy jobs in the private sector.

Live a good life. If there are gods and they are just, they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones. -Marcus Aurelius
