Tennis is an individual sport, and I am quite a self-conscious person.
I've always been lucky enough to just play tennis, so I never actually had a job when I was growing up.
I'm definitely open to change, but at the same time I am quite stubborn.
You can't focus on other people's careers. Everybody is different.
It becomes tricky, and you start to think about the cramps rather than just actually what you're trying to do on the court, which is obviously win the match.
Give it everything you've got. Leave nothing out there.
