This work, is a letter to my friend Aloysius. In it I share a method of dominating on the tennis court by applying findings from evolutionary psychology, and sport psychology. With this letter made available to you the reader, the modern tennis player shall find a means to elevate his/her game, and dear I say also, to elevate his/her life. The letter is available in digital, print, or audiobook. The value of the letter to you, is the value of expert advice given to a friend on this current topic. Drawing on my expertise as a performance psychology consultant, and as a tennis player, I was able to provide useful insight on the game to Aloysius. I am certain that you will also find significant insights here. All the best!
