But my question is this: Does your sub-consious somehow usually force the decisions in your life to put you in the situations that fit your mental beliefs on what your life is supposed to be like? OR does your mind change and adapt your views of what your life is supposed to be like to the circumstances you end up in resulting from your choices along this path?

Either way, most people seem to feel that they are where they are "supposed to be" in life - destined to be - and keep making decisions that lead themselves down one particular life-path. (destructive, productive, empty, succesful, happy, dependent, reckless; whatever)
