What's the difference between being scared & excited?

I made a 1 minute sales presentation this weekend. It's amazing how hard it is do it that fast! Anyway, right before I did it, I checked in with myself, and found that I was right on the line between scared and excited. So I wondered, what's the difference between fear and excitement.

It's very simple --if I have a positive expectation, then I'm excited. If I have a negative one, then I'm scared.

Try it yourself -- right now, think about something that's coming up that could be great -- or not. When you project a great outcome, how do you feel in your body? When you project a negative outcome, how do you feel? And which is the better way to go? Wouldn't you rather project a positive outcome and feel better?

And when you think of the Law of Attraction, which is that what you focus on, expands, wouldn't you rather stay positive? If you attract what you focus on, why wouldn't you focus on the positive?
