Hey, how's it going everyone. I need all your help, seriously, in developing an effective game. I've been told by many that I am very "talented" and have all the shots in the book by many. I have big serves, great groundstrokes, consistency and good footwork. Yet I manage to crash and burn in many of my matches because my mental game is quite crappy. I'm condescending, a quitter/tanker, etc. Really just a terrible person on the court. I desperately want to make a change for the better, so maybe a little tips here and there will be well appreciated. Don't be afraid to get personal or make assumptions. I'm open to criticism. Thanks!
