I was attending a week-long summer camp that required campers to attend two "tracks" during the week. These tracks consisted of sports, music, crafts, and so on. My best friend saw a pretty girl sign up for tennis, so he asked me to sign up for tennis with him as his "wingman" of sorts.
While he tried (fruitlessly) to flirt with the girl, I began learning the fundamentals of the game. As soon as I returned home, I went to Walmart and bought a Wilson Mach 3.
12 years later, I'm absolutely obsessed with the sport.
Get in where you fit in.
