Doing the things I do

Can anyone tell me why am I doing things that brings my hopes high up into the clouds and then dumping it onto the hard cold concrete despite knowing it all that the probabilities of anything happening in that scenerio is closer to the estimation of 0.000000000000000000000000000000000000000001?

It seems like I love doing things like this and then spend the day pondering over why I did so.

OUT! :S
