Hello, I'm new and still swallowing.

I'm worried my personality type is holding me back with women. I am a ISFJ, which is also known as the protector. The wiki page says I'm greatly concerned with the security of others and they often find assisting the downtrodden or people with disabilities to be satisfying and that I am not as sociable as other role variants and uncomfortable being in positions of authority. I can also seem cold apparently.

This makes me worried because it seems to be the exact opposite of what red pill says I should be like. I've been going to the gym to lift more (I always did running but haven't lifted weights before last week) but now I am worried that the basic parts of my personality will hold me back.

Has anyone successfully changed their personality? What should I do to change the core of my personality?
