For Those Who Teach

If you are one of those who teaches, and you are feeling discouraged, or that what you are doing really doesn't matter: go to Netflix, and look for episode 102 of the original Twilight Zone series (season 3, episode 37, "The Changing of the Guard").  In some respects, it is very un-PC, but I suspect that few who teach will be able to watch it out with getting teary-eyed, and perhaps a bit more willing to see that we do makes a difference--even if it takes a very long time, and we may not see all the results.
