Wish me luck

Saturday I am presenting an interpreting workshop to what now looks like 50+ people. I'm trying not to think about it too much so as not to get too nervous. But it's still there in the back of my head worming its way around. I'm ready, more or less, with the things that I need to bring: PowerPoint, handouts etc. I just wish I could convince my nerves that I'm ready. I'm sure it will be fine, but I'm a worry wart and that's what I do. So if by chance you get a moment and are thinking about it send some positive vibes my way, I would really appreciate it.
