When you were little did a grown up tell you when you grow up you can be whatever you want to be*?
Yea...that was a lie...Sorry! Fate, Karma, the alignment of the stars, pine cones, whatever, all get in the way and you become just who you are, not always who you wanted (or want) to be
There comes a point where all you can do is laugh-hysterically, uncontrollably, until you begin to weep or can't breathe and snot begins to run down your face...
*Also, "you have so much potential" is code for Life=Fail
