One of the issues of thought is that its like a machine learning ruleset but by the time we are of age to contemplate how our own conscious thinking works, the whole thing is nearly undecipherable to the subjective self. Hamming describes well, we do what we do. Machines do what they do. Now if strict rules are followed, wheres the thought?

At a strictly information theoretic approach to intelligence, I think we can agree that decision making is the atom of intelligent life or intelligent machines. Since consciousness is (insert spiritual uptick here) but moreso a geometric effect, ie. Every being feels their conscious space somewhere in their body (most likely the head.) the only individuality one can really find is of experience, and therefore memory, and therefore ammo for decision rules.

Quantum physics also is nice in that it allows for any possible physical arrangement for the next moment in spacetime, although the highly unlikely physical interactions are well...unlikely.

So if "destiny" of a human being is quantum effects in both the brain and reality providing randomness. And birth and body providing genetics, epigenetics, a starting ruleset. The closest we can come to crediting ourselves as decision makers, is that we follow pretty logical Darwinian-evolved logic. And quantum physics lets us add the outliers and the absolute exclusion set of programming as a reality. I like to see free will as (well at least the experience is not controlled by anyone else) hey..randomness is a free spirit. Physics, nature, "The Great Animator" might not even possess knowledge of the future because of quanta. Its also an implication for time travel, if quanta are reversed, the they may flatten to different bits. Ride the wave! :-)
