Men are raised to be proud of their accomplishments, and they're taught to promote themselves. That's one of the main reasons they make more money than women. Women, *especially* women of her generation (guessing from the "Grammy" part of her business name) were taught to be humble about their accomplishments, and to downplay themselves. (I know I don't need to tell you this... you know!) Women of MY generation were raised by enlightened women of her generation who had learned that the role they'd been raised in was bullsh*t, and did their best to teach us to take pride in our accomplishments... but we still have a hard time, because our mothers could *tell* us to be proud and to promote ourselves, but they still, unconsciously, were living the old way and could not *show* us.
We all need to try consciously to display these skills. Some women (Tink!) are really good at it, and set a good example for the rest of us.
