As long as you can imagine different possible futures and decide upon which one you want to try and realize, I think you have choice.
Choice stems from uncertainty, partial knowledge. It might be an illusion for an observer outside of the system, but as far as a participant within the system is concerned, there is choice, then there is free will.
I am writing this because I ca n but I don't need to do it. I have futures where I don't do that and do something more rewarding instead and still. As long as I am aware of the choices, then I have free will.
Just because it feels as though I do things because I can doesn’t mean that is actually true.
