I have always strived to be as self sufficient as possible. If there is something I don't know, I will learn about it. If my car starts making clunky sounds as I drive over bumps, I'll get under it and have a look. About the only thing I won't do unless I have no other choice is have someone else take care of it for me. In life, not having to rely on other people is what I'd consider true freedom. I know realistically this "true freedom" is not something that I will ever fully achieve unless WW3 or the zombie apocalypse occurs, but it sure doesn't stop me from trying. I love the satisfaction of being able to rely on my own knowledge and skills to get me through most of life's obstacles.
Any of you other INTP's feel the same way about being self sufficient?
