I'm trying a new thing this weekend, and I'm adrenalized--jumpy, my heart beats quickly and my blood feels fizzy. That is, I'm a little fearful, a lot excited, and very tentative.
It would be easy to interpret the physical arousal state into just one emotion, like fear, but I'm choosing to be excited about the possibilities. I look forward to this weekend as an adventure that will test me in certain ways. I'll learn a lot whether I have a good time or a bad time.
