I know!! it's an amazing "trick", isn't it? I agree it's not just high heels and all that pretty lady shazam. I hate being the pretty clueless girl when it comes to it also :)

I want them to think I know exactly what I'm doing.

See, to me this is a fantastic little tool - you're making yourself think you know what you're doing by making others think that. This isn't a question of whether you know or not, but often, we know what we're doing, but lack the confidence to show it and that digs into our ability.
