Why we do not learn !

I am surprised that with the large amount of information flowing around, why we do not learn. I think half of us do not think we need to learn ! We think we already know everything and it is just that we are already there to teach it to others. While we are all set to teach others, there are a few audience to listen to learn !! Next is most interesting that there are so many learning opportunities that people do not bother to take up and learn something !
