Yes, he is very good at inspiring people. I have seen his videos on kelbytraining.com and I have his book. I highly recommend getting his book, as it goes over most of what he talked about in the seminar. Excellent reference, one of the best books I've seen that goes over every little detail, talks about his gear, lighting,etc.
We didn't leave until after 11pm as his flight was delayed from Phoenix to Dallas because of the weather, so I didn't get to talk to him directly, but it was worth every penny.
