I can do this.
I drove north, found the hotel (Well, after I got lost near campus. Freaking one way streets and wrong addresses.), checked in, parked the car, unpacked and finished one of the two last slides. I had dinner with Dave - which was delightful and distracting - then came back to the hotel to finish the last slide and shower.
I'm sleepy, so I'm going to rest. I've decided on which of the 4 outfit choices I brought will be worn tomorrow. I will wear contacts and curl my hair. The talk is done and I feel good about it. Tomorrow is full of meetings, and I can handle people one on one without freaking out.
I feel - strangely enough - calm and focused and confident. So keep thinking good thoughts (or doing whatever it is you're doing). I do believe it's working.
