You literally don't, unless you had control of the "starting point" being your birth. One cannot make an action of their own without the influence of the external forces upon oneself. This isn't a bad thing, it's just reality and even studying this brings awareness to how God cannot even have own will. Once again that's not a bad thing.

It's a bit strange to think that the one who is powerful enough to not only create the universe but sustain its existence with just as much power every nanosecond would be unable to stop things from happening within creation if it were against his will, or unable to make something happen within creation if it were in his will.
