I always hated that "If I could help/change-for-better/gotten-through-to/have-heart-to-heart one child each year, I'VE SUCCEEDED!" quote that some teachers use.
I mean... That means you could have FAILED HARD at teaching/interacting for 95% of your students and still feel satisfied with yourself!
95% would be if they only helped one kid out of a 20-kid class... give or take depending on the size of the class.
And frankly, THAT BULLSHIT DON'T FLY IN KAXEN-LAND.
...Well, I'd be a little disturbed if bullshit flew through the air at all...
