well, I guess it would be my stubbornness I think.....but I am not sure if I really would be great without. It helped me to make it through life - not going into detail here about my life, but while it sometimes hinders me from being open towards other ways and suggestions, I feel a certain "pride" it in for the fact that it helped me when I needed it most. - In other words, your weak characteristics can also be a great asset to you. Which leads me to to another question - is there really any such trait as a bad trait or characteristic?
We all have them and should accept them as a part of who we are. This would also help a lot of people who feel negative about themselves. Accepting the bad as well as the good in you helps feeling good about yourself. Like you had mentioned everybody has it's "ghost in the closet". So why even bother to hid and feel bad? A characteristic that is bad in one situation might be great in another.
