The reason for my actions starts and ends in my human will
That doesn't make any sense at all - it's literally meaningless. Either you will things for reasons or for no reason (or a combination).
But our gift of free will gives us the power to override what most appeals to us if we so wish.
On one level, of course but the wish to override something that appeals to us must be because there are reasons that actually make overriding it more appealing to us.
You can't escape the infinite regress. Your version of 'freedom' is nonsense.
We all have consciously driven control over much of what we do - we are not automated machines with no will of our own.
Yes - but that wouldn't be true if your version of freedom was true - we'd either never make any choices (because you've excluded all the things that can decide matters) or we'd be acting randomly.
