One important thing to know about free will... Absolute free will would mean we make every choice completely anew, without any influences. This is impossible of course.
What are the possible influences for our actions? I personally can only our intrinsic properties, outside influence as the cause of our actions. Anything else would amount to randomness.
The intrinsic properties are a important thing to note though. They limit our free will. We can't have intrinsic properties while having true free will to be anything we want. And it needs to be that way. Because intrinsic properties.. is our identity, our personality. Our way of making choices defines us as a person, makes us a individual. It's the natural order of things. And besides, it needs to be this way to make decisions properly. If we would decide every action completely unbiased, we would sit in the same place all day, stare, or get killed by animals. It's no way to live.
