Teaching Zumba

I am seriously thinking about becoming a Zumba instructor. I'd need to complete the Zumba training, which shouldn't be too difficult. Then I might need to complete some other courses, depending on where I'd teach. I already have a dance background and I really love the official Zumba class I attend on Saturday mornings. I guess I'm just not very confident in myself right now. (Not to mention that I'd need to get together like $200 for the training course.) Maybe I should just take a deep breath and plunge in. It might be good for me. (Better than asking "what are the best diet pills" at least!) After all, I'd be doing something I love instead of something that drains me every day. That's good, right?
