What is humility? As usual, CS Lewis gets it right:
To even get near [humility], even for a moment, is like a drink of cold water to a man in a desert.
Do not imagine that if you meet a really humble man he will be what most people call “humble” nowadays: he will not be a sort of greasy, smarmy person, who is always telling you that, of course, he is nobody.
Probably all you will think about him is that he seemed a cheerful, intelligent chap who took a real interest in what you said to him.
If you do dislike him it will be because you feel a little envious of anyone who seems to enjoy life so easily. He will not be thinking about humility: he will not be thinking about himself at all.
