Remember that someone else's lack of appreciation or good manners or grace or compassion or sense of fairness really has nothing to do with you and everything to do with them. People treat other people the way they treat themselves. So why make it about you?
Just stay true to your own moral instincts. Display the virtues of being positive, honest, goodwill, excellence, humility, forgiveness and respect to all, with a clear understanding that very few will ever acknowledge your integrity and stainless character. Do good anyhow.
