I'm going to jump!

So our first open house workshops are next week. I have the folders printed, I have practiced my presentation (to myself, the dog, a mirror and the furniture - hopefully the women that come will be a bit more engaged). The problem - I don't know who's coming, what if nobody comes? Nah, I know my friends will be there - but they don't actually count - no offense friends. I know what we've written is great. I know that it's going to be fun. I am trying to tell this meanie in my head to be quiet - a little fear is normal before you jump off a cliff, right????
