Answer: If I do what I want, it means that my desire manages me. If I do what I do not want, this is already a question.
How can I do what I do not want? This can only be if the upper light influences me. If I still do something, it means that my desire has changed, which means that I already want to.
So, freewill eventually brings me to a point where I do what I do not want to do. It is in this state that my freewill is expressed.
