[El Gran Salseron]

"she is successful and proud of it."

Successfully ruthless?

That's what you mean, isn't it?

[Naomi4]

Successful men are ruthless frequently. When women are all sorts of labels get attached to them that are less than flattering.

Martha Stewart built an empire. My guess is she is a perfectionist and often is difficult to work with.

If she was a man she would be praised for toughness and the competitive spirit.
