I've spent weeks preparing a presentation for a national conference. After all of this work I thought I was ready but, to be on the safe side, checked my notes one last time. Two weeks had passed since I last read the outline. When I read it again I realized several points were out of order. I made these corrections and read the outline yet again. To cut down on the number of pages, I shortened several points. At last, my talk is ready, and my handouts are ready too. Tomorrow I fly to Tampa. Despite heavy rains and flooding, the airport is open, and I hope many people come to the conference. The moral of this story: It never hurts to check one more time.
