Because you are doing something because of them. You say they stem from experience and choice, but where does choice stem from?

There is also intuition, logic, inspiration and not based on experience that can also influence our perceptions; and our perceptions influence our experiences. I suspect one could say that the logic and inspiration are based on experience. However, given an immediate problem to solve in which there is no basis in the past, there are times in which we have no frame of reference from the past and are isolated; we must rely on natural inherent mental acuity to problem solve our ways out of regardless of any experience. Also inspiration, there is some inspiration that comes from and becomes an experience, but other inspiration that is "other worldly" for lack of a better term or "divine" as another way of putting it, that cannot be explained by experience that can decide things for us, call it fate. Once happens, it could be considered an experience from that point forward. However the initial occurrence of fate's influence, I personally cannot discount, the way the world works in sometimes making decisions/choices for us.

Choice is the result of an accumulation of information from experiences.
[I] In knowing how so many things have shaped my decisions and choices in the past, there is no denying that experience can shape choices but I owe my life in one particular instance not to things that have shaped my past but to mental acuity and problem solving, inspiration, and intuition, not withstanding experience. There are some situations that we are thrown into that we have no frame of reference for experience from our pasts. It was not past experience that saved me from an attacker and rapist; it was quick thinking to use an object you never would have thought of to injure him within inches of his life, intuition, will to live, and the inspiration that he was not going to the better of me that I fought him; I had no frame of reference for this experience as it had nothing to do with past experiences. My reactions, inspiration, and perception of wanting to live is what influenced my survival to help me make choices to do so, in turn affecting my experience. It was not the influence or accummulation of past experience that that saved me, but inherent will to live perception causing me to choose to fight, and being provided with intuitive and problem solving skills to affect the outcome of my experience. .
