I do not think future holds a predetermined course. But events and such influence and predetermine the near future. 

I think then our actions are contingent upon the reality in which we live. We have free will inside this reality, but we are not free to choose whatever we want or whichever action we want to take ignoring the physical realm. (Our we could but the outcome might not be good for our physical selves). 

The further off the reality, the more we can choose. The near future is more determined than the distant future. A balance as you say.

But then also randomness. It doesn’t matter how hard we choose or manifest. Suddenly the universe has set in motion a car running into you or lightning electrocuting you. You could not have seen it coming, or had any meaningful will to avoid it.

I think the quantum physicists discussed this. Bohr etc. in fact didn’t they say multiple realities exists. One reality for every possibility.
