Sitting shotgun

Does it ever seem like you are just a passenger in your own life?  Think about all the variables in life that you have absolutely no control over, but still leave a lasting impact of how you live.  If you clearly can't control anything other than your actions, what in life have YOU actually chosen?  Are the people you surround yourself with put there by you, or are they there merely by coincidence?  In a world where even the decisions you do make are pre-made, pre-packaged, and spoon fed to you, what can truly be changed or controlled?  I'm just not content with sitting shotgun in my own life any longer, time to take the wheel and finally learn how to drive.
