NTJs are very rare, I am unconvinced about your typing there.
E vs I in this system is dominant function's orientation (extro vs intro). You don't seem like ambivalent?.. Could see ISFP I guess, since with good Se ISxPs pass for social stereotype of extroversion. Extroversion doesn't imply that you are ready to socialize every mINUTE OF YOUR LIFE.
I could be wrong about Ne part but I can't see Ti>Fe preference in anything you wrote at all. I've collected various quotes about Ne here. There's Se vs Ne there too, at the bottom.
