Hi William.
I guess if it is a defect that bothers you, just keep working at it. You are aware of it, want it to change, and to me , that is success in the making.
I have some of that, er, I like to call it determination, and I have always considered it a good thing. I don't give up easily, and like to have perfect results, on some things. It has be a good thing most of the time.
That perfectionism has probably saved you , in many ways. maybe being disappointed in yourself is the defect to lose? I think you are amazing. 85- I can't believe it-
take care. and I hope that I did not say anything dumb, since I am just beginning to learn boundaries and codependency.
