Enjoy this video from the First Lady's Chief of Staff. I love her words: "You're there for a reason, you have a point of view."
Click the blog title to go to the website if you're viewing this in a format that doesn't show the video. It's worth watching.
I particularly like the way she talks about waiting for an opening to move the conversation forward, and how her colleague was oblivious to how she masterfully turned the conversation around.
Yes - you need to speak up. And how you do it matters.
