Heads or Tails

In today's world so much is feasibly possible, so many options exist in the grand scheme of things, but how much is truly attainable by the individual. How much of that is determined by the individual and how much is a circumstance of the myriad of independent variables that surround us on a daily basis? How many factors does our own brain's activity control? I realize I am throwing darts at the dark night sky hoping to hit a bulls-eye that is light-years away or perhaps doesn't exist at all. I've just been feeling as though I am just part of one big cosmic coin toss after another and that's all there is to it, no justice surrounding it or any karmic principles that lead to future events. However I feel as though this is a typical response to a "hard time" for an individual, whereas if I had been experiencing amazing things in the past few years, then maybe I would lean more towards believing that my "good actions" had led to my good fortune. That, in and of itself, makes me feel more and more like I really am just a giant coin in the universe, being flipped over and over, along with everyone else...where will we land?
