I think there is a difference between privacy and secrets.
I think privacy is stuff you want to keep to yourself in a healthy way.
I think the term "secrets" has a bad connotation.
I've heard some people say "No more secrets here! I'm going to tell my boss tomorrow I'm an alcoholic. He'll appreciate my honesty." Not so fast. I think this is an example of confusing secrets with privacy. I think the most successful people in life keep their privacy for the most part.
