There is this short story in "To cut a long story short" by Jeffery Archer which I though I'll put down here. Its about how the grass is always greener on the other side for nearly everyone be it rich or poor. It started with the thoughts of a tramp who used to sleep at the side of a bank. Though he was fine & not miserable with his condition, he thought how lucky the door keeper of the bank was etc etc. Then it proceeds to the thought process going on in the door keepers mind, who was thinking how lucky the person sitting inside at the reception was, who didn't have to stand whole day long & do a mind less job. Then story moves on to the thought process to that persons mind who was thinking how lucky some officer was who had just gone past him. That officer was thinking about his own monetary problems & kid problem. This officer then eyed his senior as lucky who in turn was brooding over his family problems. This officer also eyed his senior who also had his own problems n so on. Finally even the CEO of the bank had just mailed his resignation to the board as he could not continue having made some major mistakes in corporate decision making. And finally while this CEO was leaving the bank after resigning, he looks at the tramp & thinks how lucky this tramp was, doesnt have to deal with all this & that he would be so happy to switch places with that tramp.
Thus the circle completes. Each one finding the grass greener on the other side...It was really nicely written :)
