One can choose not to change one's future? No, one definitely can't.
As demonstrated merely by my choice to not change my habit of non-smoking, I change nothing about my future relative to avoiding the many maladies directly related to smoking, which has far more consequence3 to my eternity than moving my hand on a given impulse. Come on, we're talking economies of scale here, on which you argue an infinitesimal degree to which I say, simply, in a thousand years, let alone more, who the hell cares a tinker's-dam? Yeah, look it up; the significance of the dam is very small. Not worth the words I've already devoted to it.
Tell me which other thing than your choices and your experiences can affect your choice.
Expectation. The virtual opposite of experience because expectation always directs to a future not yet experienced. It is the seed material of goal-setting, else, why make them? Yes, P1 fails.
randomness, mind controll or divine intervention, the things that would prevent free will from existing.
How does randomness prevent free will? There are choices to be made that may not make significant effect on a future. We're back to the tinker and his dam. So what if I choose, at random, to wear red boxers or blue? Tomorrow, green or white? Repeat the next day, or choose black or yellow? Who's going to know, but me, but, further, who cares? God? Not in the slightest will he care even if he knows. What, he's going to send me a mind-message that on Wednesday, I'd better wear pink, because I'm going to visit my Mother, and if I don't...? Well, even God knows that a woman scorned.... As I said, the tinker and his dam in the eternal perspective. Yes, it is percentage points less than 100% unshakable. How many is of no consequence, but, it's more than 1%. Yes, P2 fails.
Whether or not you chose to smoke...
Yes, my current condition is due to experience and character, but that says nothing about my choice to change either or both, and that decision is difficult to prove was made by random selection and neither predestination, nor absolute free will based on any past behavior, character, or experience. Yes, C fails, but mostly because either one, or the other, or both have failed in addition to being a circular logic, which, by definition, because it leads to nothing but itself, isn't logic.
