I don't think this is possible, especially if factors such as (genetical, physiological and environmental) are involved.
"I simply do not like change."
Even change you orchestrate yourself?
"Funny you should say that, I changed my name a month ago. I hated the one I had."
Legally?
"Because, I like the way I am. I don't want them getting their hands on me and turning me into something different."
So don't use "them", aspire to change yourself. If you don't see how you can improve, other people's perspectives can help for looking outside of your filter, outside of your boxed perspective, even find advice from similar thinkers of how they've improved. To think you're already at your peak is to allow yourself to stagnate, it invites sloth, and will overtime make for losing any edge you have. Striving to improve will at the very least help keep you sharp even in failure.
There's always room for more, even if that "more" isn't one other people like.
"And I have to ask. You have the exact resemblance to a psychologist, are you??"
Pfff, I wish.
Do you honestly believe that telling everyone you had a different name allowed you to "leave your past behind"? A superficial change only provides temporary, shallow reprieve. You appear to be largely governed and constricted by your fears. "Wherever you go, there you are." What are you running from?
