I've always been challenged by Lewis description of Humility. A humble person is someone who constantly focuses on others rather than him/herself. It is also someone who willingly admits that pride is everlurking in his/her heart. He writes in Mere Christianity:
"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.
If anyone would like to acquire humility, I can, I think, tell him the first step. The first step is to realise that one is proud. And a biggish step, too. At least, nothing whatever can be done before it. If you think you are not conceited, it means you are very conceited indeed."
Makes me realize how far from humility I really am...
