By saying every thing in your life is random due to you CHOOSING to do a different action every time shows that your free will does exist and each decision creates its own circumstances hence your life is all randomed up. I dunno if that makes sense to you but i see your logic.
I am actually saying that our choices are determined by all the random or determined things happening around us. Thus all your "choices" are determined no matter what, and you can't shape the future in more ways than one.
But yeah, like I said before; I am really not certain, obviously. But right now it seems logical.
