If we follow this logic, then Stephen Hawking achieved free will, since he was not anymore in charge of his impulsive voice and body

But i still feel like i am doing my actions randomly and that i am thinking randomly, like if i someone else Is using my mind and he or she Is manipualting my brain cells or voice in order to do that. But following this logic, I AM that Person that Is controling my mind and all this time i acted randomly and impulsively, and i should accept the fact that i will never achieve total control over my brain chemicals.

Yeah, stopping a repetivie action, thinking deeply or talking slowly are the only existing free actions.

I have an answer for the question "Is free will real": Since the time we are born, we are exposed to repetivie behauviour: waking up, having breakfast, getting dressed etc. At some point, these actions become almost completely instinctive, like if they were completely unintentional and separated from real will. We should also consider that, if you feel like you have no free will, It means that you realized that you have no complete control over your brain or body. And this also proves that the mind is different from the brain.

I came to the conclusion that I, according to the Dunning-Kruger effect, have a severe cognitive impairment.
