Almost 30 years ago (wow, that sounds just plain awful) I was a walk on to a D1 school, and worked at the indoor courts on campus (front desk, stringing, etc) and the coach was kind enough not to kick my sorry rear end out of practice. Periodically just through perseverance and others dropping off I got a sniff at #6, but was never good enough as the other kids. I'd never played junior tennis, and was basically self taught, so I desperately wanted to play, but I was also a Mechanical Engineering major- and man did my grades suffer. If I had to do it all over again, or offer any advice to others, if the individual doesn't have exemplary time management skills, give it another think. Two years of grad school and not touching a racket later, after getting my first real job and joining the company tennis club,
I still remember walking on to court with the then senior VP of HR. Such is the beauty of tennis.
