If every move made is pre-determined, how free is your will?

Purely from a psychological standpoint, if we base everything off of past positive/negative outcomes, then wherein lies our will to unsoundly make decisions that go against what our mind has taught us? Therefore freedom is a touchy subject because it states that we can easily move between boundaries our mind has/has not set, and that reinforcement does little to change us.

which in turn would argue the ability for people to change. Change would actually be seen as more of a repression of past actions. We are still creatures of habit.
