Here are some very humbling and wise words from C.S. Lewis,
"If you want to find out how proud you are the easiest way is to ask your self, 'How much do I dislike it when other people snub me, or refuse to take notice of me , or shove their oar in, or patronise me, or show off?' The point is that each person's pride is in competition with everyone else's pride. It is because I wanted to be the big noise at the party and I am annoyed at someone else being the big noise."
It's true, everyone's pride is at war with everyone else's pride. But who am I to think that I am the greatest and the best or even think that I am even sort of great? I am nothing, I can't even do a simple thing like draw breath without God's help.
I found this quote to be very helpful in helping me to identify pride in my every day life.
