If you publish enough and get enough people to look at you, you will somehow convince people that you are an authority on your subject, and some of those people might ask you to be on television. Most recently, friend and occasional guest blogger was on CNBC last night, talking about her book Hedge Funds for Dummies. You can check her out here. Doesn't she look great? I chatted with her on what she learned from the experience that might help you out when you're invited to be on Anderson Cooper or what have you.

·How's your hair"I called my hairdressed the minute the gig was confirmed. I don't trust myself. I think that as long as your roots are done, you look like you're making an effort."

·Wear solid colors and consider your audience"They always say to wear solid colors. I wasn't sure whether to play it fashionable or to play it safe, but since I figured I was talking about business, I'd wear a jacket."

·Put on some makeup"I did my own makeup, with foundation and powder--I actually worried that I put on too much powder, but then somebody at the studio told me that there is no such thing as too much powder when you're on TV."

·Pretend it's not weird"I was told that people either freak out or act like they don't mind that they're on camera. I had an earpiece feeding me audio and I had to look into a camera and pretend I was talking to someone, so I just pretended like I was talking to someone on speakerphone."

·Prepare "I had a pre-interview, so I knew some of the things they might ask me, but I also knew they might ask me a few stuff that would be completely different."

·Think before you speak "I had to make an attempt to stop and breathe every time I felt myself about to say "um" or "like" or 'whatever.'"

·Get there early. "They wanted us to be there 15 minutes early. We got there 45 minutes early."
