Sorry or Aggrivation - cause no matter how hard you try to get ahead, something or someone can come by and knock you back to the begining...
I would also throw twister into the fray, seems like you have to tie yourself up in knots and worm your way over, through and under people to get ahead....
Alas... if only life could be a game of naked twister....
