Practice Procrastinating

I'm supposed to be practicing for the job interview I have on Wednesday morning. I've got to put on a presentation that will last for 15 minutes. The work is done; the power point is spectacular and the speech is nice and engaging. I just can't get myself to practice it all the way through for some reason. I stop as I'm going to look at something else and then I pick up and go back to it. This time, I stopped because I wanted to add a black slide for the pause. I need to learn it all. I'm afraid I'm going to end up knowing the first three slides really, really well but I won't know the last half at all.
And how on earth am I supposed to concentrate on practicing the speech when there are so many more exciting things to do? Is this a sign that my speech is boring? Or is it because I am too stressed out about the prospect of failing that I can't bring myself to prepare? UGH! Why are life goals always so darn hard to achieve? Not to say that being a trainer for a cell phone company's customer care is what I always wanted to be, but it is close - I'll get to teach someone something important. And in a small way I get to leave my mark on the world. It brings me a lot of satisfaction. I'd love for it to be my real job. But here I am ticking away at my keyboard, rambling about not being prepared and procrastinating… totally defeating my own purpose.
I guess I'll get back to it. My fingers just needed a stretch. Now, I will FOCUS and get my presenting on.
