In the last five years, what have you become better at saying no to?

What I'm not willing to accept is the enduring status quo around maternity. I asked Nike to contractually guarantee that I wouldn't be punished if I didn't perform at my best in the months surrounding childbirth. I wanted to set a new standard. If I, one of Nike's most widely marketed athletes, couldn't secure these protections, who could?

I communicated that I wanted to skip press conferences at Roland Garros to exercise self-care and preservation of my mental health. I stand by that. Athletes are humans.

I just felt like it would be a little bit better to take a back seat, work on my mindfulness. And I knew that the girls would do an absolutely great job and I didn't want to risk the team a medal for kind of my screw ups because they've worked way too hard for that. So I just decided that those girls need to go in and do the rest of the competition.

But these days, if I have to choose between building my tennis résumé and building my family, I choose the latter.

I'm tired, I'm not myself and I'm not enjoying the sport as I have done for the last decade. Some might recognise it as burnout; I just know that over the last few years I haven't had the answers.
