What and why are we doing this???

A very obvious and straight question which some or the other time haunts me is :" why am i doing this" and " what am i doing". Every one of us has been some or the other time questioned self. But we do not have time to look for an answer. Is it not? We are busy doing something which most of us do not want to do. So why are we doing it?

We do things because every one is doing or someone has taught that or may be because we have no idea about it???? This is funny but true........ !!!
