so, my high school has tennis tryouts on tuesday and wensday. i'm feeling excited and nervous at the same time. i've been praticing for a long time and especially up-ed it this week. i hope my tennis practice has gone to good use. one of my main fears is chocking and not doing as well as i know i can do. do you have any advice in keeping my cool? people say i have potential to make varisty this year (and btw, this is my first and last year for tryouts, i am a senior in high school). any help would be greatly appreciated!
