I remember walking with a former girlfriend who played tennis at SU years ago. She refused to take a pair of the cheapest headphones of all time for free from someone promoting an on campus event that week.
Waking up hours before most students to practice or work out, breakfast, classes for hours, lunch, meeting with trainers or staff, then maybe more class, practice after or a match, dinner, homework, bed.
All while being forbidden making any money or taking anything from people. Wild stuff and requiring a whole lot of dedication and sacrifice FOR A NON REVENUE SPORT.
