Dennis, I never dated a whole lot while I was single. I did some dating, of course, but things really didn't fall into place for a while. That all changed when I was invited to a New Years party through a friend of mine. I firmly decided that I intended to do NOTHING else but be myself and have fun.
With that attitude in mind, I went out, bought new clothes (at the time I was at my lowest adult weight) and went out looking sharp. My now-wife was hosting the pre-party, then we were going to a club. I wound up hooking up that night in a big way. In hindsight, it was the attitude that I was just going to enjoy myself, look good and not worry about impressing anyone that was the source of that. The confidence that gave me turned out to be far sexier than any of the other stuff.
