I used to be like that, I used to think everything hinged on my every perfection, and was (relatively) petrified at the idea I'd be forced to allow some lull in the conversation and therefore my life would be over. The more I dated, and the more often I met people with whom I had great chemistry, the more I realized that if the conversation doesn't come naturally it's a good sign there's nothing there and the date's a wash in the first place.
