I think there's a time in your life where you don't feel like you fit in. I think everyone has that when you're a teenager especially and especially in the society we live in.
It is never too late to get into tennis! While I started playing at the age of 8 when my parents gave me a tennis racquet for Christmas tennis is a lifelong sport that can be enjoyed by people of almost any age. It's also something you never forget once you learn.
