Me Myself

Your ability to change yourself is in your nature. You still had to do the work, but you also just admitted that the ability to change yourself was part of your nature. You plugged into this innate ability and did the necessary work. Free-will doesn't mean freedom from doing the actual work. It's the stuff that gives you the ability to do the work.
Of course we have the ability to change our own nature, w chnge it to what we are predetermined to change it when we are predetermined to change it according to the stimuli of the environment and our genetic info.
