All you can, the best you can do, is to humanize yourself, to continue on with the processes that follow from education.  (To the Buddhist, the 'thatness' of things and people.)   This is what Paul, for instance, was doing, when he stopped persecuting and took up writing his letters.  It's as if he had always wanted to write, to think about the deeper things, like charity.  It's as if he wanted to be generous, rather than accusatorial.  Perhaps he surprised himself, the hidden riches of the human mind when applied to being human.

Other people will not always care, so it seems, if you yourself humanize yourself, if you become 'a mensch.'  Other people will not even seem to notice.  Maybe they make it seem like your deep humanity is simply their due.  A customer could easily say, well, your polite service, kind, is what you are being paid for, not thinking far beyond that, as they turn back to their phone, 'buy, buy, sell, sell, what were you saying, honey?'  The great skeptic.

It can be in every fiber of your being, to follow through with the great humanity residing within, waiting to be cultivated, to flourish.  But it is also easy to forget about, easy to sweep aside in favor of more comfortable things, more selfish things.  And it is hard to convince oneself that one is even doing a remotely capable job of it, that one can even do anything that would amount to much at it.  "For all that work, but a drop in the bucket have I produced."

"Playground fairness, that is the best we can achieve," the cynic.  "And rules of fairness were meant to be broken, by the strong and the crafty."

But humanizing sees humanizing.  A step toward potential helps one see the greater possibilities, which then lead one to self realization.  Even if it goes on unseen, unnoticed....
