'Thank you' is the best prayer that anyone could say. I say that one a lot. Thank you expresses extreme gratitude, humility, understanding.
The first condition of humaneness is a little humility and a little diffidence about the correctness of one’s conduct and a little receptiveness.
A man is never so proud as when striking an attitude of humility.
Humility is not thinking less of yourself, but thinking of yourself less.
True humility is not thinking less of yourself; it is thinking of yourself less.
