The ratings adjustment in November seems to have done some wonderful things. It has swept away all of the 3.5 and 4.0 guys who made me miserable in mixed with their twist serves, their topspin, their pace and their consistency. It has swept away all of the 3.5 women who used to upstage me in about every match, making it look so easy. So, for the first time since I started playing tennis, I feel like I can and should win. Like today. I played 7.0 mixed, and I didn't have any trouble returning the guys' serves, or rallying with them. Every now and then, they would have trouble with my serve. It felt different, and it felt good. I am bursting with confidence, feeling like if I just do what I do, I should win and have an awesome season. Which sounds dangerous. And a bit cocky, honestly. To those of you who found yourself at the top end of your ratings bracket, how did you keep your head together? I mean, anyone can beat anyone on any day, right? Nothing is a sure thing, especially in doubles, right? So do you walk onto the court feeling like no one can beat you, or do you walk on feeling like no way you can lose? You think maybe when Federer takes the court he thinks deep inside that there is no way the guy on the other side has a prayer?
